  From the Yahoo! Search Blog:

  By supporting semantic web standards, Yahoo! Search and site owners can bring a far richer and more useful search experience to consumers. For example, by marking up its profile pages with microformats, LinkedIn can allow Yahoo! Search and others to understand the semantic content and the relationships of the many components of its site. With a richer understanding of LinkedIn’s structured data included in our index, we will be able to present users with more compelling and useful search results for their site. The benefit to LinkedIn is, of course, increased traffic quality and quantity from sites like Yahoo! Search that utilize its structured data.

  But I’m still struggling to find an way to make my sketches (the wordpress posts) more semantic and structured. I have the following questions:

  • Should I use RDFa or microformats or both?
  • How do I embed semantic information, by hand in the WordPress code editor or are more sophisticated tools or plugins available?
  • What is the roadmap of WordPress towards Web 3.0, e.g. are there plans to support RDF like the Drupal community is planning to do?

  So the semantic web puzzle is still missing some important pieces, mainly on the end-user side of things…

  Virtuoso OpenSource Edition Introduction

  OpenLink Software announces the open source licensing of most of its Virtuoso product. All the database, WebDAV/web server and SOA functions of Virtuoso are part of the open source release. There is a commercial release which additionally features virtual database and replication capabilities.
  What is Virtuoso?

  At core, Virtuoso is a high-performance object-relational SQL database. As a database, it provides transactions, a smart SQL compiler, powerful stored-procedure language with optional Java and .Net server-side hosting, hot backup, SQL-99 support and more. It has all major data-access interfaces, such as ODBC, JDBC, ADO .Net and OLE/DB.

  Virtuoso has a built-in web server which can serve dynamic web pages written in Virtuoso’s web language (VSP) as well as PHP, ASP .net and others. This same web server provides SOAP and REST access to Virtuoso stored procedures, supporting a broad set of WS protocols such as WS-Security, WS-Reliable Messaging and others. A BPEL4WS run time is also available as part of Virtuoso’s SOA suite.

  Virtuoso has a built-in WebDAV repository. This can host static and dynamic web content and optionally provides versioning. The WebDAV repository is tested to interoperate with WebDAV clients built into Windows XP, Mac OSX and others and makes Virtuoso a convenient and secure place for keeping one’s files on the net. Further, Virtuoso provides automatic metadata extraction and full text searching for supported content types.

  OpenLink Virtuoso supports SPARQL embedded into SQL for querying RDF data stored in Virtuoso’s database. SPARQL benefits from low-level support in the engine itself, such as SPARQL-aware type-casting rules and a dedicated IRI data type. This is the newest and fastest developing area in Virtuoso.

  All stakeholders are part of the audience for the design rationale. Stakeholders are the people who are affected by design decisions sooner or later. And there will be a time when stakeholders want to hear explanations why certain design decisions were made, e.g. when:

  • the designed system is malfunctioning;
  • the designed system must be adapted;
  • the designed system must be scaled up or down;
  • the designed system or parts of it must be renewed;
  • the designed system is more expensive then expected.

  Different stakeholders are looking from different viewpoints and will have different views on the design rationale.
