Proposed properties (summary / stats properties) for discussions

[Breslin, John]

Hi all -

Based on the efforts at the Drupal RDF(a) code sprint here in DERI, I am asking for feedback on a few new properties that are similar to some existing ones like num_replies.

I'd value your opinions. Many of these can be of course derived from other data but they would provide nice summaries that could be used e.g. in a search such as http://www.google.com/search?q=best+irish+pubs+boards

num_threads
The number of Threads (AKA discussion topics) in a Forum.
Domain: sioc:Forum; Range: xsd:integer

num_posts (or else num_items)
The number of Posts (or Items) in a Forum (or a Container).
Domain: sioc:Forum (or else sioc:Container); Range: xsd:integer

last_post_date (or else last_item_date)
The date and time of the last Post (or Item) in a Forum (or a Container).
Domain: sioc:Forum (or else sioc:Container); Range: xsd:dateTime
subPropertyOf: dcterms:date

num_authors
The number of unique authors (Users and unregistered posters) who have contributed to this Item, Thread, Post, etc.
Domain: owl:Thing; Range: xsd:Integer

num_replies (*already exists*)

last_reply_date
The date and time of the last reply Post or Comment. This could be associated with a starter Item or Post, or with a Thread.
Domain: owl:Thing; Range: xsd:dateTime
subPropertyOf: dcterms:date

Thanks,

John.

Do you have some use cases to back up the usefulness of those
properties, e.g. fields like that in Drupal?

Those make sense to me. How about range: xsd:nonNegativeInteger?

Maybe subPropertyOf dcterms:modified? Although that's a bit wonky, I
admit. :-)

Also range: xsd:nonNegativeInteger.

Should that be a subPropertyOf num_posts/num_items?

And should that be a subPropertyOf last_post_date/last_item_date?

Yep, to annotate column data from a page such as
http://sioc-project.org/forum or http://sioc-project.org/forum/10 with
RDFa.

>> num_*

Yes, and could change num_replies range too.

>> last_post_date (or else last_item_date)

Yes, it is a similar idea (the Forum was last modified through the
creation of new content within it).

>And should that be a subPropertyOf last_post_date/last_item_date?

Regarding these two, I don't know - the domain for the sub-types are
different (either greater than or of a different type) than the
super-types so I'm not sure it'd work... E.g. num_replies applies to
maybe a post or a thread whereas super-type num_posts is for a more
restricted forum/container, and last_reply_date could be for a post,
thread or even a forum whereas super-type last_post_date is for a more
restricted forum/container.

Dear all -

It's taken some months but I've committed these additional properties.

Change log: Added num_authors, num_items, num_threads, last_item_date,
last_reply_date. Changed XMLSchema#integer to
XMLSchema#nonNegativeInteger.

If there are any errors, please let me know.

Thanks,

John.
