Re: [Tei-council] standOff problem #1: content model of <teiCorpus>

In reading and rethinking this, I am trying to remember our line reasoning in wanting TEI to be a member of model.resourceLike, and not including teiCorpus there. I think we did want to preserve a semantic distinction between the two, didn’t we? Our current explanation of model.resourceLike is that it “groups separate elements which constitute the content of a digital resource, as opposed to its metadata.” In the context of a TEI document that is a child of a teiCorpus, does this mean we consider TEI the “content” of the digital resource, as opposed to the “metadata” of the corpus as a collection? And yet in a context without a corpus collection, we would consider the TEI element to contain both metadata and content. To make teiCorpus a member of model.resourceLike seems like we are saying it, too, can be considered a content level element as opposed to a metadata element. I am finding this worrisome, because it seems like we are just opening these two elements up to meaning two contradictory things. Either they are content-only, or they contain metadata and content. Somehow I would rather they both could be seen as always metadata-bearing on principle. Were we thinking of changing the explanation of model.resourceLike to accommodate the bearing of metadata in the TEI element? I don’t think this is just a fuzzy terminological matter and find myself unexpectedly disagreeing with Martin here. I think the distinction between content and metadata is something we ought to consider here: can we no longer tell a difference between metadata and content in a standoff context?

I’m really sorry not being able to join you later (to bring it forward myself) but please have a look at ticket https://github.com/TEIC/TEI/issues/1823 and PR https://github.com/TEIC/TEI/pull/1922 where I already tried to tackle the content model of teiCorpus. The problem we faced (and still seems evident with Syd’s proposal) that teiCorpus would allow a structure like <teiCorpus xmlns="http://www.tei-c.org/ns/1.0"> <teiHeader> ... </teiHeader> <text> ... </text> </teiCorpus> which we thought was not intended.

I agree with Syd on this: teiCorpus should be a member of model.resourceLike. The fact that as a result TEI and teiCorpus become essentially the same thing is actually a plus for me. I think any line drawn between the two is terminological rather than structural, and while it might be clearly delineated in the case of particular projects, in the broader view it's very fuzzy indeed.

This is exactly the same as saying teiHeader, model.resourceLike*, ( TEI | teiCorpus )* except that it requires at least one child <TEI>, <teiCorpus>, <facsimile>, <fsdDecl>, <sourceDoc>, or <text>. In the new <standOff> world, we have voted to make <TEI> a member of model.resourceLike. Thus we have to alter the content model of <teiCorpus> because as written it would be ambiguous (if a <TEI> is your first child after <teiHeader>, you don't know which branch of the content model you are in). It is not too difficult to solve the ambiguity problem: teiHeader, ( ( model.resourceLike+, ( teiCorpus, ( TEI | teiCorpus )* )? ) | ( teiCorpus, ( TEI | teiCorpus )* ) ) ) I am pretty confident this content model validates the same set of documents (and, perhaps as importantly, rejects the same set of documents) as the original content model (with <TEI> in model.resourceLike). I am not against using this content model. But it occurs to me that a) it is a bit cumbersome b) the set of documents permitted is already screwy c) it looks very different from the content model of <TEI>, which (in the new world order) <teiCorpus> is very similar to. One possible solution is to 1) add <teiCorpus> to model.resourceLike, too; and then 2) change content model of <teiCorpus> to match that of <TEI> (in the new standOff world): teiHeader, model.resourceLike+ This has the advantage of having a very clean, understandable content model for <teiCorpus> (and no ambiguity). It has the disadvantage that it allows for even more screwy things. E.g. <teiCorpus> <teiHeader> <standOff> <TEI> <facsimile> <TEI> <teiCorpus> <TEI> <facsimile> <TEI> <teiCorpus> <facsimile> </teiCorpus> It has the feature (which some will consider an advantage, others a disadvantage, I'm sure) that <TEI> and <teiCorpus> become the same thing. Just as an XSLT stylesheet can have an outermost element of xsl:stylesheet or xsl:transform, no difference, a TEI document will be able to have <TEI> or <teiCorpus> as an outermost element, no difference. Same goes at every level of nesting where one is allowed: so is the other, and it can have the same content. Personally, I still think putting <TEI> into model.resourceLike was probably a mistake, but once we've done that, I'm inclined to say throw <teiCorpus> in there, too. _______________________________________________ Tei-council mailing list Tei-council@lists.tei-c.org http://lists.lists.tei-c.org/mailman/listinfo/tei-council
