Turn off the rdf List generation?

[danbri]

Is there a way to turn off the list generation?

e.g. the example from http://schema.org/TVSeason

... is there a way to avoid all the first/rest stuff?

Well... the generation 'simply' implements what is in the transformation note:

http://www.w3.org/TR/microdata-rdf/

There is value for controlling this:

http://www.w3.org/TR/microdata-rdf/#value-ordering

The registry for schema.org looks as follows:

"http://schema.org/": { "propertyURI": "vocabulary", "multipleValues": "unordered", "properties": { "additionalType": {"subPropertyOf": "http://www.w3.org/1999/02/22-rdf-syntax-ns#type"}, "blogPosts": {"multipleValues": "list"}, "breadcrumb": {"multipleValues": "list"}, "byArtist": {"multipleValues": "list"}, "creator": {"multipleValues": "list"}, "episode": {"multipleValues": "list"}, "episodes": {"multipleValues": "list"}, "event": {"multipleValues": "list"}, "events": {"multipleValues": "list"}, "founder": {"multipleValues": "list"}, "founders": {"multipleValues": "list"}, "itemListElement": {"multipleValues": "list"}, "musicGroupMember": {"multipleValues": "list"}, "performerIn": {"multipleValues": "list"}, "actor": {"multipleValues": "list"}, "actors": {"multipleValues": "list"}, "performer": {"multipleValues": "list"}, "performers": {"multipleValues": "list"}, "producer": {"multipleValues": "list"}, "recipeInstructions": {"multipleValues": "list"}, "season": {"multipleValues": "list"}, "seasons": {"multipleValues": "list"}, "subEvent": {"multipleValues": "list"}, "subEvents": {"multipleValues": "list"}, "track": {"multipleValues": "list"}, "tracks": {"multipleValues": "list"} } },

This can of course be changed/updated, but you tell us what and how...

That being said, isn't it correct that if this is serialized in Turtle, it would generate the (...) syntax? Which looks o.k....

Ack. I will try to find some time to look at it; there may be a bug...

Well,

I looked at this and, unfortunately, this is correct (again, the structure is much more visible in turtle). What happens is that the way the microdata->RDF conversion is defined is to have a top level triple of the sort

<> md:item ( item1 item2 item2 )

This is because the microdata specification is adamant on keeping the order of things as they appear in the HTML source. This is what you see in this case, although the list consists of one single entry with the reduced registry...

:-(

Gregg, I wonder whether we should not issue a new version of the note with an updated schema.org structure...

Can you suggest a hack that will make this parser emit non-List-based triples from schema.org microdata?

[iherman]

Well... honestly, I do not see anything clean. Of course, it can be removed from the code, but I would not like to do so; the implementation simply implements what the microdata model is in RDF. In other words, the only clean way would be to go 'back' to the source, change either the microdata model itself or its RDF mapping, ie, declaring the order to be irrelevant. But I do not think the implementation should deviate from the spec.

Speaking as an individual, and knowing the usage of microdata, I think the fact that the microdata specification insists on keeping the top level order is indeed irrelevant, but that is only my opinion. On the other hand, the fact that some of the terms, say, in schema.org keep the order makes a lot of sense; a good example is 'author'.

I'm not aware of anyone relying on document order for schema.org semantics. Other Microdata users might vary (but I'm not aware of any of those either).

That said, it is perfectly proper for a doc format like HTML+Microdata to say that order matters, and that in principle they could be relied on. In practice it adds so much complexity to the graph, that the simplified unordered view is super useful. And extracting such a view is entirely reasonable; it seems a shame if this tool makes it hard.

[dbs]

Per https://github.com/w3c/microdata-rdf/issues/6, the second edition of the Microtdata to RDF transform specification (https://www.w3.org/TR/microdata-rdf/) suggests that the top-level md:item should be dropped. It would be great to see the pyMicrodata parser plugin for rdflib follow that recommendation; right now I'm crawling a bunch of html and extracting RDFa, JSON-LD, and microdata into a triple store, and the md:item misdirection is a pain.

[iherman]

@dbs, I have made the changes and issues a PR for this:

https://github.com/RDFLib/rdflib/pull/443

however, this PR has never been incorporated. It seems that there were problems with the procedures to accept the PR; to be honest, I do not remember all the details. The automatic system, I believe, reported some errors that, in my view, aren't errors and we got stuck. Very honestly, I have not looked at this thing since then (more than a year) and the facts are hazy. If somebody can de-block this situation, that would be good but, really, I cannot do it these days (I pretty much moved away from RDFLib...)

Thanks for the update, @iherman -- I'll try to put some more effort into resolving RDFLib/rdflib#443 as well!
