Hello, There seem to be a few issues with the current RDF output from OpenLink Data Spaces.
1. In the RDF/XML SIOC output, like [1], the value for the sioc:content property is incorrect. sioc:content is for unformatted (plain-text) content[2], but ODS exports the HTML and *doubly* encodes it (ending up with things like "<"). The same applies to wiki pages like [3]. The SIOC spec recommends that AtomOWL or the RSS 1.0 Content module be used for formatted content. 2. When comments to blog entries are exported, their authors are given their OpenIDs as URIs. For example, see [4] and the foaf:maker assertion therein. This is probably incorrect, as OpenIDs are generally URIs for web pages, and thus cannot identify people. 3. The XHTML+RDFa generated for the pages is not well-formed[5], making it difficult to use with off-the-shelf RDF libraries (e.g. RDFLib refuses to deal with it).
