SA-REST is a simple and open microformat for enhancing Web resources with additional semantic information. In addition to HTML and XHTML, the SA-REST approach can also be used to enrich Atom, RSS, and arbitrary XML. SA-REST is one of several open microformat standards.

Although mashups fully embrace the idea of customization on the Web, read-write is another story. The complexity of application development using Javascript makes it hard for average developers to create new mashups and to customize the existing ones. To solve this problem, several companies are developing tools for mashup creation that require little or no programming knowledge. These tools, exemplified by Yahoo! pipes, IBM’s QEDwiki and Google’s Mashup Editor, facilitate the selection of some number of RESTful Web services or other Web resources and chain them together by piping one service’s output into the next service’s input while filtering content and making slight format changes.

SA-REST is a microformat to add additional meta-data to (but not limited to) REST API descriptions in HTML and XHTML. Developers can directly embed meta-data from various models such an ontology, taxonomy or a tag cloud into their API descriptions. The embedded meta-data can be used to improve search (for example: perform faceted search for APIs), data mediation (in conjunction with XML annotation) as well as help in easier integration of services to create mashups.

The W3C Media Annotations Working Group has published Working Drafts of Ontology for Media Resource 1.0 and API for Media Resource 1.0. The former document defines the Ontology for Media Resource 1.0, a core vocabulary to describe media resources on the Web. It is defined based on a core set of properties which covers basic metadata to describe media resources. Further it defines syntactic and semantic level mappings between elements from existing formats. The ontology is supposed to foster the interoperability among various kinds of metadata formats currently used to describe media resources on the Web. The latter defines a client-side API to access metadata information related to media resources on the Web.
