Blogging - why add metadata?

• Current blogs are part of the eye-ball web
• links and relations are only
• untyped hyperlinks
• trackback, pingback, etc.
• only web pages are linked, not arbitrary
  resources
  
• hard to...
• find data
• reuse data
• import data

Structure vs. Content

• Structural metadata
• Relations between blogs, posts, comments, etc.
• More than just A links to B - what kind of
  relationsship? Approval? Criticism? Mentions? Is
  about?
  
• ... relations within the blogosphere.
• Content-related metadata
• What is this post about, what is its topic?
• Anything a blog author wishes to discuss.
• ... relations between the blogosphere and
  everything else.

Structural Relations in the Blogosphere
10
Producing Metadata - Structural

• Harvest data from blogging platforms (e.g.
  WordPress, Drupal) - users, post-relations, etc.
  
• Plugins to map data in to common RDF-based
  format
  
• One vocabulary SIOC - Semantically Interlinked
  Online Communities
  
• Classes siocSite, siocUser, siocPost, etc.
• Properties siochas_creator, sioccontent,
  siochas_reply, siocreply_of, etc.

11
Producing Metadata - Content

• Reuse existing structured / semi-structured data
  from a users desktop.
  
• Blog about...
• People? - Reuse AddressBook data.
• Events? - Reuse Calendar data (iCal, Outlook,
  etc.).
  
• Publications? - Reuse data from bibliographic
  database.
  
• Content metadata is open-domain, so use any
  number of vocabularies / ontologies FOAF, iCal,
  BibTeX, ...
  
• semiBlog - Tool for doing all this!

12
Producing Metadata - Content (II)
13
Publishing Metadata - Content

• Attach metadata about posts topics to post.
• Currently
• upload as file through XML-RPC
• embed links to files in posts HTML code,
  mime-type application/rdfxml
  
• Alternatives
• Embed RDF in post
• (RDF/A, ...).
• Post to RDF-store,
• not file.

14
Publishing Metadata - Integrating Structure

• SIOC metadata is produced on request.
• Plugin discovers semiBlog links.
• Connect post and content metadata through
  foaftopic statements.

Consuming Metadata

• Semantic Web Search
• Crawling SIOC (and semiBlog) metadata using
  auto-discovery link.
  
• Store in RDF store.
• Query and Browse crawled metadata.
• The Semantic Web as a clipboard - Using Semantic
  Blogging for data exchange.
