RSS Feeds from Delaware

The State of Delaware has two new RSS newsfeeds featured by links right off the state's homepage. As lead of the team that developed the feeds, I'm pleased to report this as a joint effort of our office, the Government Information Center (GIC) and the Register of Regulations.

The first feed, Delaware.gov - Statewide News is a general collection of news and press releases from across state agencies.

The Current Monthly Register is the newsfeed equivalent of the The Delaware Register of Regulations, a monthly publication of all proposed regulatory changes, general notices, and final regulations from our partners in the Legislature.

The Government Information Center is the office that manages the state portal, Delaware.gov. The mission of the GIC is to develop and deliver accurate and complete governmental information online. The office works with state agencies, legislators, the public and others to improve the delivery of government services and information through Delaware.gov and other channels.

Create Voice-enabled RSS News Feeds

With the proliferation of RSS feeds in state and local governments, a unique opportunity is developing to expand the delivery of the critical information contained in these feeds by leveraging the most ubiquitous personal communications device in the world -– the telephone. Governments that use RSS to deliver information to citizens using RSS feeds can also leverage VoiceXML, an open standard for developing telephony applications, to expose RSS content via cellular and traditional telephones.

VoiceXML is a web technology that can turn any telephone, even a rotary phone, into an Internet device. VoiceXML is a non-proprietary, web-based markup language for creating vocal dialogues between humans and computers. VoiceXML is similar to another common markup language -- HTML, the basic language of visual web pages. Just as a web browser renders HTML documents visually, a VoiceXML interpreter renders VoiceXML documents audibly. In this respect, one can think of the VoiceXML interpreter as a telephone-based, voice browser. As with HTML documents, VoiceXML documents have web URIs and can be located on any web server. However, instead of pointing a client-side web browser at a specific URI, citizens can access a VoiceXML application by calling a toll free telephone number from any ordinary telephone - cellular or traditional, touch-tone or rotary.

It’s not hard to think of a scenario where a local government or a university could publish an RSS feed with topical news, and have a phone number for students or citizens to call for more information. Depending on how the VoiceXML is structured, the caller could have the option of being transferred directly to the number associated with the information.

The trick would be, in my opinion, finding the right place within the RSS feed to put the phone number (if the publisher wanted to provide the option of an automatic transfer). Ideally, the phone number would be contained within its own RSS element. Glancing quickly at the RSS 2.0 spec, this could be something like the guid element. So, if a publisher was using a software package to author and publish RSS feeds, they would probably need to do a little experimenting to find the right place to place the phone number.

Because RSS and VoiceXML are both XML vocabularies, there are a number of standards-based methods for converting RSS to VoiceXML and using RSS feeds from within VoiceXML applications. The first method involves the use of eXstensible Style Sheet Language Transformations (XSLT). I have created a tutorial covering this technique and some of the issues relating to it. This technique is generally agnostic to the underlying technology used; XSLT transformations are supported in technologies like JSP, PHP, Perl, .NET and others.

To see it in action there is a demo application available at (800) 289-5570. Enter the following PIN when prompted: 9991422919. This example uses the latest headlines news feed from CNET News.com (news.com.com) and the XSLT file covered in my tutorial. This is only running on a demo platform, so I can’t guarantee anything on performance. Still, it gives you a sense of how an RSS feed sounds. This technology could allow travelers only equipped with cell phones to get the latest NOAA RSS weather reports, lobbyists to dial-in for legislative floor calendars, and rescue teams to phone for the latest operational instructions.

The other method for using RSS from within VoiceXML applications is to leverage the new data tag, an addition to the VoiceXML specification that is part of the developing VoiceXML 2.1 standard. Some excellent examples of this technique can be found on the VoiceXML Forum website at http://www.voicexmlreview.org/apr2004/columns/apr2004_speak_listen.html.

VoiceXML also allows for the playback of recorded audio. If one had an audio file that they want to include in a feed, a VoiceXML application could actually invoke the audio file and play it to the caller. There is a VoiceXML service at (800) 555-TELL that plays audio files. Give it a call and try listening to the “News Center” option.

One caveat -- most VoiceXML platforms only support certain audio formats, but the more common ones (WAV, MP3) are usually supported. VoiceXML also supports recording the audio of a call, so if one wanted to let callers post comments the application could record their audio and save it for later playback. There is actually a project called “Phone Blogger” that takes this approach (see www.wombatnation.com/phoneblogger).

By using these techniques, governments that make information available to citizens through RSS feeds can dramatically expand the accessibility of these feeds by making them available to anyone with a telephone.

WordPress Uses RSS as Blog Export Format

Where to Find the RSS Specification

The RSS Advisory Board has published the RSS 2.0 Specification for 20 years, releasing 10 revisions over that time. The current version of the specification can always be found at this URL:

https://www.rssboard.org/rss-specification

The revisions have mostly been minor, aside from one clarification that namespaces can be used to extend RSS by adding elements and attributes, not just elements.

The best way to learn how to implement RSS as a software developer is to read the RSS Best Practices Profile created by the board. It includes all the rules of the specification along with our recommendations for how to handle issues that have arisen among implementers.

For example, the enclosure section describes how to deal with the biggest ambiguity in RSS: Can an item contain more than one enclosure?

The RSS specification is available under a Creative Commons Attribution/Share Alike license, so it can be republished on websites and software related to RSS and syndication under those terms.




rss

RSS Enclosure Support in WordPress

One of the biggest challenges for a software developer implementing the RSS 2.0 specification is the issue of enclosures in a feed item. The specification is infamously unclear on whether an item allows one enclosure or multiple enclosures.

The RSS Advisory Board worked on the RSS Best Practices Profile for nearly two years, investigating a lot of RSS readers and feed producers to see how they handled issues like this. We ultimately made the following recommendation for enclosure:

Support for the enclosure element in RSS software varies significantly because of disagreement over whether the specification permits more than one enclosure per item. Although the author intended to permit no more than one enclosure in each item, this limit is not explicit in the specification.

Blogware, Movable Type and WordPress enable publishers to include multiple enclosures in each item of their RSS documents. This works successfully in some aggregators, including BottomFeeder, FeederReader, NewsGator and Safari.

Other software does not support multiple enclosures, including Bloglines, FeedDemon, Google Reader and Microsoft Internet Explorer 7. The first enclosure is downloaded automatically, an aspect of enclosure support relied on in podcasting, and the additional enclosures are either ignored or must be requested manually.

For best support in the widest number of aggregators, an item SHOULD NOT contain more than one enclosure.

Because the profile was completed in 2007, it would be useful to see how current software handles RSS enclosures to evaluate whether any recommendations should be reconsidered. To start this effort the current WordPress was tested, since that massively successful platform publishes 60 million RSS feeds. WordPress enables audio files to be added to a blog post using the Audio icon in the block editor:

When three audio files were added to a blog post in WordPress, the item in the RSS feed contained three enclosure elements:

<enclosure url="http://example.com/Fanfare60.wav" length="2646044" type="audio/wav" />
<enclosure url="http://example.com/CantinaBand60.wav" length="2646044" type="audio/wav" />
<enclosure url="http://example.com/ImperialMarch60.wav" length="2646044" type="audio/wav" />

Follow this blog for more updates on enclosure usage in feeds and feed readers.

As you probably guessed, we have an RSS feed.

Every Mastodon User Has an RSS Feed

The distributed social network Mastodon has grown to 12.8 million user accounts, supporting itself through user donations and a lot of effort by the volunteers running servers. There's no CEO changing the network at whim, no ads and no algorithms that manipulate what you see to increase engagement. Just a scroll of posts by the people you follow pulled from all over the world.

Every Mastodon account has an RSS feed that can be found by going to the user's Mastodon page and adding ".rss" to the URL of that page. For example, the RSS feed for Bonaventure Software is at this address:

https://mastodon.online/@bonaventuresoft.rss

The feeds are valid RSS and use the Media-RSS and Webfeeds namespaces.

The Media-RSS content element contains the photo, audio or video included in the Mastodon post, if one is present:

<media:content url="https://files.mastodon.online/media_attachments/files/109/326/769/636/254/303/original/552ebb9fd3f30171.png" type="image/png" fileSize="49052" medium="image">
  <media:rating scheme="urn:simple">nonadult</media:rating>
  <media:description type="plain">Eli Lilly & Co stock performance graph over the last month, showing lower valuations than the one caused by the bogus announcement of free insulin.</media:description>
</media:content>

The Webfeeds icon element holds the URL of the user's avatar:

<webfeeds:icon>https://files.mastodon.online/accounts/avatars/109/298/336/948/075/673/original/e76dfce4df4bef76.gif</webfeeds:icon>

One potential improvement to the feed would be to add a link element from the Atom namespace to identify the URL of the RSS feed, as in this example:

<atom:link href="https://mastodon.online/@bonaventuresoft.rss" rel="self" type="application/rss+xml" />

That might not happen anytime soon. Mastodon is a frenetic open source project with 61 open issues and suggestions involving RSS.

How to Read an RSS Feed with PHP Using SimplePie

If you need to load an RSS feed with the PHP programming language, the open source library SimplePie greatly simplifies the process of pulling in items from a feed to present on a website, store in a database or do something else coooool with the data. There's a full installation guide for SimplePie but you can skip it with just three steps:

  1. Download SimplePie 1.5.
  2. Copy the file autoloader.php and the folder library to a folder that's accessible from your PHP code.
  3. Make note of this folder; you'll be using require_once() to load autoloader.php from that location.

SimplePie has been designed to work the same regardless a feed's format. It supports RSS 2.0, RSS 1.0, Atom and the earlier versions of RSS. Additionally it can read feed elements from nine namespaces.

Here's PHP code that loads feed items from the news site Techdirt and displays them in HTML:

// load the SimplePie library
require_once('/var/www/libraries/simplepie-1.5/autoloader.php');

// load the feed
$feed = new SimplePie();
$feed->set_feed_url('https://www.techdirt.com/feed/');
$feed->init();
$feed->handle_content_type();

// create the output
$html_output = '';
foreach ($feed->get_items() as $item) {
  $html_output .= '<p><a href="' . $item->get_link() . '">' . $item->get_title() . '</a></p>';
  $html_output .= $item->get_description();
  $html_output .= '<p>By ' . $item->get_author(0)->get_name() . ', ' . $item->get_date();
}

// display the output
ECHO <<<END
$html_output
END;

The API documentation for SimplePie_Item lists the functions that can extract data from each feed item. The versatility of the library is demonstrated by get_authors(), which can retrieve an item's authorship information whether it was in the RSS author element, Dublin Core creator, iTunes author, or Atom author.

SimplePie supports caching so that a feed isn't downloaded every time code is executed. The addition of these lines turns on caching, specifies the location of a cache folder and sets the time to use a cached version to four hours (14,400 seconds):

$feed->set_cache_location('/var/www/cache/');
$feed->set_cache_duration(14400);
$feed->enable_cache();

SimplePie was created by RSS Advisory Board member Ryan Parman, Geoffrey Sneddon and Ryan McCue. The project is currently maintained on GitHub by Malcom Blaney.

RSS Enclosure Support in Micro.Blog

An effort is underway to examine how feed publishers and feed consumers are handling the lack of clarity in the RSS 2.0 specification about whether an item can contain more than one enclosure. The RSS Best Practices Profile recommends that a feed item should contain no more than one enclosure "for best support in the widest number of aggregators," advice worth testing against current usage.

The artisanal small-batch blogging service Micro.blog is a platform for sharing short posts like Twitter, but in a way designed to be less viral, more low key and less prone to provocation, attention seeking and clout chasing. There are no follower counts, public likes or trending topics. Founder Manton Reese explained why in his book Indie Microblogging:

Big social networks like Instagram are designed to amplify accounts that gain traction, whether they are fake or not.

Micro.blog limits search and avoids public likes and reposts so that the snowball starts small and stays small. Instead of going viral and becoming a major problem, fake accounts can be spotted early and shut down if necessary.

Since being funded by a Kickstarter campaign in 2017 that hit its goal in one day, Micro.blog has attracted a dedicated following. One of the options available to premium subscribers is to host a podcast. An audio button appears below the post editing window to choose a media file.

Choosing a podcast file to add to a post

Micro.blog sites have a primary RSS feed and a separate podcast feed. The latter contains enclosure elements. Because the Micro.blog editing window does not allow more than one podcast to be added to a post, the RSS item for a post contains only one enclosure:

Has the RSS Advisory Board Followed the Roadmap?

There has been recent discussion about the roadmap that was added to the RSS 2.0 specification in August 2002 announcing that there would be no new additions to RSS, freezing its set of elements and attributes forever and ever amen. The roadmap stated, "We anticipate possible 2.0.2 or 2.0.3 versions, etc. only for the purpose of clarifying the specification, not for adding new features to the format."

The RSS Advisory Board was formed 20 years ago to publish the specification and "make minor changes to the spec per the roadmap," as stated in the launch announcement on July 18, 2003.

If you're wondering whether the board has followed the roadmap, this timeline of RSS elements answers that question. There are 44 elements in RSS. This table shows when each element was introduced, the group that added it, and the version in which it first appeared.

There were 33 elements added to RSS by Netscape in 1999 and 11 by UserLand from 2000 to 2002. No elements have been added by the RSS Advisory Board.

The rss element wasn't in the first version of RSS created by Netscape. Instead the top-level element was rdf:RDF until it was changed by Netscape to rss four months later.

Be Unique And Use RSS Guid Like Everybody Else

Winter scenes: Snowflakes by Theodor Horydczak

If you publish an RSS feed, you should do a solid for the developers of RSS readers by including a guid in each item. The guid's job is to be a unique identifier that helps software downloading your feed decide whether it has seen that item before. Here's the guid for an item on the arts and technology blog Laughing Squid:

<guid isPermaLink="false">https://laughingsquid.com/?p=914660</guid>

No other item on Laughing Squid will ever have this guid value. It's a URL that loads a blog post with the title Playful Elephant Pretends to Eat Woman's Hat. If you load the guid's URL https://laughingsquid.com/?p=914660, it redirects to the permanent link of the post. Because the guid is not the permanent link, there's an isPermaLink attribute with a value of false.

Most guid values in RSS feeds are the permanent link of the item, as in this example from the world news site Semafor:

<guid>https://www.semafor.com/article/07/07/2023/us-jobs-data-what-experts-make-of-the-new-numbers</guid>

A drawback of using the permalink is that if any part of the URL changes -- such as the title text or the domain name -- the guid changes and RSS readers will think this is a new item to show the feed's subscribers, when it's actually a repeat.

A guid doesn't have to be a URL. It can be any string that the feed publisher has chosen to be unique. Here's the guid from the RSS Advisory Board's feed for this blog post:

<guid isPermaLink="false">tag:rssboard.org,2006:weblog.217</guid>

Our guid follows the TAG URI scheme, a simple way to assure uniqueness by putting these five components together in this order:

  1. The text "tag"
  2. A domain owned by the feed provider
  3. A year the provider owned that domain
  4. A short name for the feed different from any other feed on the site
  5. The internal ID number of the post

There's different punctuation between each component. The year 2006 was when the board began using the domain rssboard.org. No one else used that domain that year, so any feed reader that stores "tag:rssboard.org,2006:weblog.217" as this item's guid should never encounter that value in any other item on any other feed.

To see how RSS 2.0 feeds are using guid, several thousand feeds were downloaded this evening from an RSS aggregator that publicly shares the OPML subscription lists of its users.

CategoryTotalPercentage
Total number of feeds4,954--
Feed using guid4,77796.4%
Feeds using non-permalinks in guid75215.2%

The term guid means "globally unique identifier," but RSS 2.0 does not require global uniqueness in guids. Because the TAG URI scheme does a good job of serving that purpose, Blogger, Flickr, MetaFilter, SoundCloud and The Register are among the sites using it in their feeds.

Tara Calishain Explains: What is RSS?

The exodus of users away from Twitter and Reddit has led many of those information refugees to discover the joy of subscribing to feeds in a reader. RSS and Atom feeds are an enormous open decentralized network that can never be ruined under new ownership -- because there's no owner.

Tara Calishain of ResearchBuzz has written a 4,000-word introduction to RSS for people who are new to the world of feeds:

I could not do ResearchBuzz without RSS feeds. They're invaluable. And I think if you learn more about them, you'll appreciate why I consider RSS the most underrated tech on the Internet. That's what this article is about: I'm going to explain what RSS feeds are, show you how to find them, go over some of the RSS feed readers available, and, finally, list several tools and resources you might find useful on your journey.

... I follow over a thousand RSS feeds which deliver information to me throughout the day. Do you think I could visit a thousand websites a day to check for new information? Even if I tried to visit a thousand a week that would be over 142 websites a day. Assuming it took me two minutes to visit a site and check for new content, I would spend over 4.5 hours a day just visiting websites.

Do you see why I'm so grateful for RSS?

Calishain, who was blogging before Netscape created RSS in 1999, covers a lot more than the basics, showing how to find hidden feeds on websites, check a bunch of feeds for freshness and create keyword-based feeds to search sites like Google News, Hacker News and WordPress. Even experienced readers of readers will learn new things, and there's a collection of nine handy RSS Gizmos she has developed.

On that subject, Calishain just began programming a year ago:

In spring 2022 I decided to find out if I could really learn JavaScript after being diagnosed as autistic. (I'm a high school dropout and didn't think I could learn something like programming.)

I CAN! And I LOVE IT!

Welcome to the not-so-secret society of programmers, Tara! Please slow down a little. You're making the rest of us look bad.

Downloading 50,000 Podcast Feeds to Analyze Their RSS

The software developer Niko Abeler has crawled 51,165 podcast feeds to study what RSS elements they contain. His comprehensive Podcast Feed Standard report looks at the usage of core RSS elements and namespace elements from Apple iTunes, Atom, Content, Podcast 2.0 and Simple Chapters. He writes:

In the world of podcasting, there is a great deal of freedom when it comes to the format and content of a podcast. Creators are free to choose their own audio format and feed content, giving them the flexibility to create something truly unique. However, when it comes to distributing a podcast, certain standards must be followed in order to be added to an aggregator such as Apple Podcasts. Additionally, the podcasting community has come to agree upon certain conventions that can be used to add additional features to a podcast, such as chapters, enhanced audio, and more. These conventions allow for a more immersive and engaging listening experience for the audience.

This website is dedicated to providing guidance and information on the conventions and standards used in podcasting.

There's a lot of interesting data in the RSS 2.0 report, which finds that these are the six least popular elements in an RSS feed's channel:

Element Usage
docs 8.3%
cloud 0.0%
rating 0.0%
skipDays 0.0%
skipHours 0.0%
textInput 0.0%

Over 99 percent of feeds contain the optional channel element language and the optional item elements enclosure, guid, pubDate and title. Only 0.2% of feeds contain a source element in an item.

The iTunes namespace report shows a lot of variation in support. The required element itunes:explicit is only present in 18 percent of feeds and four optional elements have less than 20 percent: itunes:new-feed-url, itunes:block, itunes:complete and itunes:title. One namespace in the report, Podcast 2.0, has been proposed by Podcastindex "to provide a solution for problems which previously have been solved by multiple competing standards" and is still under development.

The report also analyzes the audio files enclosed in the podcast feeds to determine their format, bitrate, channel and loudness. The report finds that 95.6 percent use MP3 and 4.4 percent AAC/M4A. People who like an alternative open source format will be oggravated that its sliver of the pie graph is so small it can't be seen.

If Abeler isn't tired of crunching numbers, one thing that would be useful for the RSS Advisory Board to learn is how many of the feeds contain more than one enclosure element within a single item.

The RSS Advisory Board Just Turned 20

"Tomorrow we will run faster, stretch out our arms farther."

Today is the 20th birthday of the RSS Advisory Board, the group that publishes the RSS specification. It was formed on July 18, 2003, when the copyright of the specification was transferred to Harvard University, which immediately released it under a Creative Commons license and deferred all matters related to RSS to the new board.

At the time of the board's launch, here's how the founding members described its purpose:

Is the advisory board a standards body?

No. It will not create new formats and protocols. It will encourage and help developers who wish to use RSS 2.0. Since the format is extensible, there are many ways to add to it, while remaining compatible with the RSS 2.0 specification. We will help people who wish to do so.

What does the advisory board actually do?

We answer questions, write tech notes, advocate for RSS, make minor changes to the spec per the roadmap, help people use the technology, maintain a directory of compatible applications, accept contributions from community members, and otherwise do what we can to help people and organizations be successful with RSS.

This remains the purpose 140 dog years later. In addition to maintaining the current RSS specification, we are the official publisher of Netscape's RSS 0.90 and RSS 0.91 specifications and Yahoo's Media RSS specification.

We also offer an RSS Validator and RSS Best Practices Profile containing our recommendations for how to implement the format.

There's a resurgence of interest in RSS today as people discover the exhilarating freedom of the open web. Some of this is due to dissatisfaction with deleterious changes at big social sites like Twitter and Reddit. Some is due to satisfaction with Mastodon, a decentralized social network owned by nobody with more than one million active users. As long as there are social media gatekeepers using engagement algorithms to decide what you can and can't see, there will be a need to get around them. When someone offers an RSS or Atom feed and you subscribe to it in a reader, you get their latest updates without manipulation.

Here's to another 20 years of feeding readers, unlocking gates, helping developers adopt RSS and repeatedly getting asked the question, "Can an RSS item contain more than one enclosure?"

How to Read an RSS Feed with Java Using XOM

There are a lot of libraries for processing XML data with Java that can be used to read RSS feeds. One of the best is the open source library XOM created by the computer book author Elliotte Rusty Harold.

As he wrote one of his 20 books about Java and XML, Harold got so frustrated with the available Java libraries for XML that he created his own. XOM, which stands for XML Object Model, was designed to be easy to learn while still being strict about XML, requiring documents that are well-formed and utilize namespaces in complete adherence to the specification. (At the RSS Advisory Board, talk of following a spec is our love language.)

XOM was introduced in 2002 and is currently up to version 1.3.9, though all versions have remained compatible since 1.0. To use XOM, download the class library in one of the packages available on the XOM homepage. You can avoid needing any further configuration by choosing one of the options that includes third-party JAR files in the download. This allows XOM to use an included SAX parser under the hood to process XML.

Here's Java code that loads items from The Guardian's RSS 2.0 feed containing articles by Ben Hammersley, displaying them as HTML output:

// create an XML builder and load the feed using a URL
Builder bob = new Builder();
Document doc = bob.build("https://www.theguardian.com/profile/benhammersley/rss");
// load the root element and channel
Element rss = doc.getRootElement();
Element channel = rss.getFirstChildElement("channel");
// load all items in the channel
Elements items = channel.getChildElements("item");
for (Element item : items) {
  // load elements of the item
  String title = item.getFirstChildElement("title").getValue();
  String author = item.getFirstChildElement("creator",
    "http://purl.org/dc/elements/1.1/").getValue();
  String description = item.getFirstChildElement("description").getValue();
  // display the output
  System.out.println(">h2>" + title + ">/h2>");
  System.out.println(">p>>b>By " + author + ">/b>>/p>");
  System.out.println(">p>" + description + ">/p>");

All of the classes used in this code are in the top-level package nu.xom, which has comprehensive JavaDoc describing their use. Like all Java code this is a little long-winded, but Harold's class names do a good job of explaining what they do. A Builder uses its build() method with a URL as the argument to load a feed into a Document over the web. There are also other build methods to load a feed from a file, reader, input stream, or string.

Elements can be retrieved by their names such as "title", "link" or "description". An element with only one child of a specific type can be retrieved using the getFirstChildElement() method with the name as the argument:

Element linkElement = item.getFirstChildElement("link");

An element containing multiple children of the same type uses getChildElements() instead:

Elements enclosures = item.getChildElements("enclosure");
if (enclosures.size() > 1) {
  System.out.println("I'm pretty sure an item should only include one enclosure");
}

If an element is in a namespace, there must be a second argument providing the namespace URI. Like many RSS feeds, the ones from The Guardian use a dc:creator element from Dublin Core to credit the item's author. That namespace has the URI "http://purl.org/dc/elements/1.1/".

If the element specified in getFirstChildElement() or getChild Elements() is not present, those methods return null. You may need to check for this when adapting the code to load other RSS feeds.

If the name Ben Hammersley sounds familiar, he coined the term "podcasting" in his February 2004 article for The Guardian about the new phenomenon of delivering audio files in RSS feeds.
