With RDFa, you can easily include extra "structure" in your (X)HTML to indicate a calendar event, contact information, a document license, etc… RDFa is about total publisher control: you choose which attributes to use, which to reuse from other sites, and how to evolve, over time, the meaning of these attributes.This site tracks RDFa specifications, implementations, and news of all sorts. If you have an RDFa implementation, add it to the wiki.

Semantic Desktop with KDE Nepomuk aims to provide the basis to handle all kinds of metadata on the KDE desktop in a generic fashion. This ranges from simple information such as tags or ratings over metadata extracted from files to metadata that is generated by applications automatically. RDF, the Resource Description Framework, provides the powerful basis to store and query all this data. The goal is to categorize all metadata using clean ontologies to make an automated handling and enrichment of the data possible.

The journal Semantic Web - Interoperability, Usability, Applicability (ISSN: 1570-0844) brings together researchers from various fields which share the vision and need for more effective and meaningful ways to share information across agents and services on the future internet and elsewhere. As such, Semantic Web technologies shall support the seamless integration of data, on-the-fly composition and interoperation of Web services, as well as more intuitive search engines. The semantics - or meaning - of information, however, cannot be defined without a context, which makes personalization, trust, and provenance core topics for Semantic Web research. New retrieval paradigms, user interfaces, and visualization techniques have to unleash the power of the Semantic Web and at the same time hide its complexity from the user. Based on this vision, the journal welcomes contributions ranging from theoretical and foundational research over methods and tools to descriptions of concrete ontologies and applications in all areas.

Automated Text Analytics Saplo provide organisations with valuable information extracted from large quantities of text

The graph api allows you to quickly and easily read data from Freebase.com

FluidDB is a platform for the web of things, each represented by an openly writable "social" object.

How can we provide access to information services that are available only in English(or Dutch, German, French, etc.) to people who do not speak this language, or not good enough to understand everything they need to know? Monnet will be concerned with providing solutions for this, using a novel combination of automatic machine translation and Semantic Web technology. The project is a joint effort between four European research institutes, German software giant SAP, Dutch company Be Informed - specializing in knowledge-based solutions for public sector information services - and standardization organisation XBRL-Europe - defining the standard for financial and business reporting across Europe.

Paggr is a novel online application that combines Linked Data with simple semantic agents and personalized dashboards. Paggr enables the intuitive creation of ad-hoc mashups from the growing amount of structured and self-describing ("smart") data on the Web.

"Semantic Web Bookmarks Created by Aaron Bradley.

What It Means Amplify is a web service that brings human understanding to content.

Yebol's mission is to build human-like world's knowledge base and provide knowledge based search (semantics) and services. Yebol utilizes a combination of patented algorithms paired with human knowledge to build a Web directory for each query and each user. Instead of the common "listing" of Web search queries, Yebol automatically clusters and categorizes search terms, Web sites, pages and contents. Yebol allows for a multi-dimensional search result instead of the normal one-dimensional search seen by most web search engines today. This provides a more accurate summary of top sites and categories; a wider array of related search terms; a longer and richer expansion for query results; and a deeper base of links and keywords in search result pages.
