Index of XML standards
The world of XML is vast and growing, with a huge variety of standards and technologies that interact in complex ways. It can be difficult for beginners to navigate the most important aspects of XML, and for users to keep track of new entries and changes in the space. XML is a basic syntax upon which you develop local and global vocabularies. This index provides a detailed cross-reference of many XML standards, including links to additional coverage for each.

Using the Twitter Search API
Twitter is undoubtedly one of the most recent and successful examples of social networking to appear on the World Wide Web. Twitter also has its own search engine, which enables users to search for "tweets" by keyword or category, with an API to facilitate programmatic searches, act as a REST service, and return searches in Atom format. Discover the basics of using the Twitter Search API.

Creating an Atom feed in PHP
Atom is an Extensible Markup Language (XML) specification that identifies information contained in a Web site. Using Atom, Web developers produce feeds that enable other Web developers (or consumers who use feed readers) to quickly locate and view information of interest on a remote site. Think of it as a Web site's index, available to anyone who wants it. Using PHP, a popular language of choice for most host providers, a Web developer can easily produce an Atom feed that can then be made available to the various feed readers and other Web developers. The ultimate result is a state-of-the-art information solution that enables the Web content to reach a much wider audience.

Feed your site with RSS and Atom
For modern Web 2.0 sites, the ability to mash up information from
different sources is a plus. You can use Google Web Toolkit (GWT) to get and
process XML-based news feeds such as RSS and the more modern Atom Syndication
Format. In this article, explore methods to access any appropriate feed -- despite
same-origin policy (SOP) limitations -- and to process the incoming XML
data.

Make dashboards with XQuery
Many digital dashboards that cropped up in the 1980s were horrible (if not unsubtle) analogs to a car's dashboard. Very few presented business data in a compelling manner. Today, Web-based dashboards try to achieve the same thing. Discover what makes a good dashboard, and learn to identify and leverage key performance indicators (KPIs) for more effective digital dashboards. Finally, build a Web dashboard using the eXist XML database and XQuery.

Use HATS to generate Atom feeds for mainframe applications
Mashups, a critical component of Web 2.0, aggregate feeds
from many applications to generate new content. Because many
of today's core enterprise business applications run in
mainframes, the content in mainframes must be delivered as
feeds before mashups can be successful in the
enterprise. This article presents a step-by-step guide to
using IBM WebSphere Host Access Transformation Services
(HATS) to generate Atom feeds for mainframe content.

Aggregate RSS and Atom information using XQuery
XQuery makes it much easier to merge and filter information from XML documents
when you embed the filtering instructions right into the document that you use to
generate the output format. You can use that functionality to aggregate information
from RSS and Atom feeds into the format you need. In this article, look at the
structure of the RSS and Atom formats and how XQuery can simplify the display of that information.

Convert Atom documents to JSON
Converting an Atom document to JSON might, at first, appear to be a fairly
straightforward task. Atom is, after all, just a bit of XML and XML-to-JSON
conversion tools are widely available. However, the Atom format is more than just
a set of XML elements and attributes. A number of subtle details can make proper
handling of Atom difficult. This article describes those issues and demonstrates a
mechanism implemented by the Apache Abdera project to convert Atom documents into
JSON and produces a result that is readable, usable, and complete.

Tip: Organize content with Atom categories
Atom lets you provide an easy way to manage lots of data, but there will come a point at which you need to add some sort of categorization to make that data manageable. This tip shows you how to use categories with Atom feeds and the Atom API. Although you will naturally add category information to information syndicated using Atom, this tip focuses on these categories from the perspective of the Atom Publishing Protocol.

Create a
sidebar using an Atom service document
An Atom service
document is for more than just telling readers where to find a site's feeds. This
article shows you how to use this introspection document to create a sidebar that
provides a window into everything your server has to offer. This article uses the
Blogapps server, which supports draft 10 of the Atom Publishing Protocol 1.0
specification, but will be applicable to any APP 1.0 compliant server. To use the
actual code, you should also be familiar with Java programming but you can apply the Atom concepts to any programming language.

Tip: Use Atom's structure to avoid duplicates in aggregate feeds
Atom is a growing syndication format favored by many over the major syndication format, RSS. With any indexing system like Atom, you never want to intentionally create duplicate feeds as this can overwrite the older, original id element. And duplicated entries (if they aren't overwritten) waste hard disk space. But more importantly, duplicate content confuses search engines, which can cause your rankings in the search engines to suffer. This tip shows you how to take full advantage of the id tag as the main identifier, including other information about the feed entry (like the link id and source URL for the feed), to avoid duplicates in your Atom feeds.

Managing XML data: Tag URIs
Uniform Resource Identifiers (URIs) can identify things without necessarily locating them. XML namespace URIs are the most obvious such use, but many others abound. When you use URIs primarily as identifiers, it's important to create URIs that are globally unique without implying that they reside on a particular server. Tag is a simple algorithm for creating unique, easy-to-remember URIs while avoiding conflicts. This has important implications for RDF, Atom, and other systems that use URIs as identifiers.
