• How do I know/model the applied version of an ontology specification? http://www.semanticoverflow.... データ記述に用いたオントロジーのバージョンを示す方法について。同じ件を思案中なので注目しておく (original post at 10:57)
• セマンティック・ウェブやLODの説明は「型付リンク」から入ると理解されやすい。"start from html w/ href, then typed link being href + rel, then how that's a triple" @webr3 on swml (original post at 10:20)
• Internet World mail interview with Tim Berners-Lee
  By the "understanding" part I assume you are talking about putting more machine-understandable semantics into the web. This will start with typed links -- we have been prototyping a discussion system for example with the WIT (W3 Interactive Talk) experiment. This addition of semantics is going to be essential if computers are to more of the work for us in manipulating this web, as at the moment it's only people who can read it - by TimBL, 1994 (original post at 10:11)

• DBpedia 3.6 released http://blog.dbpedia.org/2011... 2010-10/11版Wikipediaに基づいて350万以上の"thing"をRDF化。いくつかのプロパティの名前空間が変更になっているので、利用アプリケーションは注意 (original post at 22:55)

• Linked Data/RDF/SPARQL Documentation Challenge http://memespring.co.uk/2011... LODとかOGDとか言ってもプログラマが普通にデータを使うためのドキュメントがなければダメダメ、と啖呵を切ってちょっと話題の記事 (original post at 00:25)

• EulerGUI project
  EulerGUI started as a GUI for the EulerSharp.sourceforge.net Euler/SEM/EYE reasoning engine, and still is. The sources can be N3 (Notation 3), RDF, or OWL, UML, eCore, plain XML, XML Schema, files or URL's, SPARQL queries. Internally everything is expressed in the convergence language N3, that allows to express facts, classes and properties, and rules. It is becoming a lightweight IDE for Artificial Intelligence - by Jean-Marc Vanel (original post at 13:32)
• Documenting SPARQL extension functions http://lists.w3.org/Archives... 拡張関数URIにecmascriptをリクエストするとJSソースを返す案。関連：TimBLのフラグメントID解釈 http://lists.w3.org/Archives... (original post at 12:19)
• 住所の表現をめぐるlod-mlスレッドの中で、TimBL曰く《vCardは（社会的実体を表現する）グラフのノードではなく、グラフを保持するRDF文書の方にうまくマップできると思う》http://lists.w3.org/Archives...（カードと人の議論にも関連☞@_masaka） (original post at 10:26)

• XML5 [Anne’s Blog]
  in line with recent “jokes” about HTTP5, SVG5, and CSS5, XML5 makes perfect sense. The idea of XML5 is to provide a revision of XML 1.0, XML 1.1, Namespaces in XML 1.0, Namespaces in XML 1.1, and RFC 3023, that is backwards compatible and introduces HTML-like, although much more sane, error recovery - by Anne van Kesteren, 2007-10-23 (original post at 16:04)
