Subject [jira] [Commented] (ANY23-67) Microdata extraction using obsolete RDF conversion scheme
Date Wed, 09 Apr 2014 01:26:15 GMT

    [ https://issues.apache.org/jira/browse/ANY23-67?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13963695#comment-13963695
] 

Lewis John McGibbney commented on ANY23-67:
-------------------------------------------

>From some conversation with Ian Hickson "We ended up dropping this feature because the
Microdata and RDF data models aren't compatible enough for it to make sense to make a generic
conversion from one to the other. The solution these days is to define the mapping at the
vocabulary level."

> There is now a more-or-less final Microdata to RDF algorithm published[1] which is different
than the one in the current, official HTML5 draft [2] (that Ian Hickson has publicly revoked).
However, Any23s extractor uses the old scheme according to a comment in its source code, which
refers to [2]. However, this is exactly the algorithm that Ian Hickson rescinded at some point.
Unfortunately, the official working drafts have not been updated for a very long time, but
if you look at the editor's draft [3], you will see that that section has been entirely removed.
Instead, there was a Semantic Web Interest group task force that discussed the issues, and
[1] is the result of this discussion. It would be nice if this would be reflected in Any23
in the future.
