Is the Semantic Web necessary (and feasible)? [Kingsley Idehen's Blog Data Space]
"The question right now is: what's the equivalent driver for the Linked Data Web bearing in mind the initial Web bootstrap. My answer is simply this: Open Data Access i.e., getting beyond the data silos that have inadvertently emerged from Web 2.0" - interview by Jana Thompson with Kingsley Idehen, 2008-08-29 (original post at 13:20)
FOAFのモデリングを、RDFの意味論に沿って示した図を作成して、サロゲートを用いるモデリングとの違いを説明。メール書くのに2時間かかった (original post at 02:03)

RDFの「名前の解釈＝対象世界」というモデルと、抽象的な実体を「記述」（あるいはトピック）というプロキシを通して扱うモデル。似ているようだが、一段階違いがあるというところから、話が難しくなるようだ (original post at 23:57)

ns-schema.xslで、Deprecatedのみの子要素があるときに一覧ツリーが崩れる（空ul要素ができていた）現象を修正 (original post at 14:56)

某主題件名標目表のRDF表現について、修正案に対するコメントを作成中。モデルの問題、構文上の問題、両方あって、かなりややこしい (original post at 23:42)
@cygri, CC license needs its URI because it is defined with RDF. You're right you don't have to give a URI to your idea behind your post (original post at 01:53)

it's good that xhtml:license "refers to a resource that defines the associated license" since people can link as well as assert semantics (original post at 13:29)
we need more ways to make use of Subject Indicator (a document that describes a thing) so as to embed semantics as a link in (X)HTML (original post at 13:07)

RDFa Best Practices [RDFaWiki]
lists best practices to follow when using and developing RDFa websites, tools and applications, including sections: Authoring RDFa, Creating RDF Vocabularies (original post at 15:45)

Linked Movie Data Base
LinkedMDB publishes linked open data using the D2R Server. The project aims at publishing the first open semantic web database for movies, including a large number of interlinks to several datasets on the open data cloud and references to related webpages. (original post at 00:23)

BSBM With Triples and Mapped Relational Data
the really interesting part with BSBM is mapping relational data to RDF. For us, BSBM is a great way of showing that mapping can outperform even the best triple store (see also a thread at public-lod@w3.org) - by Orri Erling, 2008-08-06 (original post at 22:04)
Will The Semantic Web Have a Gender? [ReadWriteWeb]
we'd better watch out who is building it and what perspectives they take into consideration. Unconsidered assumptions could lead to a real disconnect between the meaning that machines know of the world and they way that millions of other people experience it - by Marshall Kirkpatrick, /w Corinna Bath, 2008-08-07 (original post at 14:36)

ARC Triples Visualizer Plugin
generates graphviz files and images of RDF graph (an ARC triples array) (original post at 23:16)

GRDDL, bridging the interwebs? [Vimeo]
Flash Video interview by Marcos with Harry Halpin, who talks about the use cases for GRDDL, an alternative way to view the Web, and gives some great suggestions as to how we can bridge the HTML Web and Semantic Web divide - 2008-08-03 (original post at 22:26)

Pimp My CrunchBase API - Semantic CrunchBase
a browser-based tool for creating tailored API calls by combining SPARQL with input parameters and output templating (original post at 23:40)

DERI Pipes
DERI Web Data Pipes implement a generalization which can also deal with formats such as RDF (RDFa), Microformats and generic XML; provides a rich web GUI where pipes can be graphically edited, debugged and invoked. (original post at 12:25)
