Subject: [OASIS Issue Tracker] Commented: (OFFICE-2577) Public Comment:Multiple RDF files and the Single XML document
[ http://tools.oasis-open.org/issues/browse/OFFICE-2577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18940#action_18940 ]
Michael Stahl commented on OFFICE-2577:
----------------------------------------
1. Multiple RDF files
Unlike, say, HTML documents, ODF documents are not meant to be produced by one
application and then displayed by another application. The main use case for
ODF documents is that they are loaded by an office application, modified, and
then stored again. This means that metadata is not only added and displayed,
but may also be edited and removed.
Now assume that some component of the application that handles some kind
of metadata wants to remove its metadata from the document.
If all the RDF statements are in one graph, how does it find out which
statements it should remove?
If it removes too few statements, then the user may have a privacy issue.
If it removes too many statements, then unrelated components may break,
because their RDF statements are gone.
Because RDF vocabularies may be reused, different components of an
application (or different extensions of an application) may reasonably use
the same predicates and types in the RDF statements they add.
By giving each component their own RDF graph in the document, we can
isolate them much better, thus enabling modularization.
Deleting all metadata of one component simply means removing its RDF graph.
Furthermore, consider the possibility that a document has more than one author.
I am not sure if there are performance advantages to having a single RDF file.
Maybe an application is only interested in a single RDF graph; such an
application would perform better in a multi-file design, because it need
not load all triples, but only the manifest and the file it is interested in.
So there is no need for change here.
2. RDF in flat file ODF
Indeed it is currently not specified how RDF metadata could be stored in a
flat
file ODF document.
Some clarification regarding the future (if any) of flat file ODF
documents would be helpful.
