[jira] [Commented] (ANY23-67) Microdata extraction using obsolete
RDF conversion scheme
[ 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."
> Microdata extraction using obsolete RDF conversion scheme
> ---------------------------------------------------------
>
> Key: ANY23-67
> URL: https://issues.apache.org/jira/browse/ANY23-67
> Project: Apache Any23
> Issue Type: Improvement
> Components: microdata
> Affects Versions: 0.7.0
> Reporter: Hannes Mühleisen
> Fix For: 1.0.0
>
>
> 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 However, this is exactly the algorithm that Ian Hickson rescinded at some point.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.
