Hi Daniel,

Your message did end up being copied to this list, but it was back in April: https://lists.w3.org/Archives/Public/public-opengov/2015Apr/0010.html <https://lists.w3.org/Archives/Public/public-opengov/2015Apr/0010.html>

Yes, please re-use Popolo where possible, and please let me know what you think needs to be extended. Popolo is not written in stone.

There is no OWL yet, but the ontology is not very large, and everything is documented on the website. If you need to create an OWL file   for Popolo for your own purposes, I’d be happy to post it on the website.

In terms of using the W3C namespace or your own namespace, I will try now to advance things with Phil so that we don’t have any unnecessary duplication.

In terms of your ontology:
1. For relations, why are you not using http://vocab.org/relationship/ <http://vocab.org/relationship/> ? It has ancestorOf, childOf, descendantOf, parentOf, siblingOf, spouseOf.
2. Elective_Office seems similar to org:Post, and Member_Role seems similar to org:Membership. Have you had a look at http://www.w3.org/TR/vocab-org/ <http://www.w3.org/TR/vocab-org/> ? Popolo reuses the ORG ontology extensively. I think you can subclass those classes and add any new properties that you need. For example, there’s org:memberDuring instead of :start and :end, org:postIn instead of :electedTo, org:heldBy instead of :officeHolder, org:subOrganizationOf for :isPartOf, org:hasSite for :region.
3. I’m not sure why there are these three properties for relating a Person to an Organization: :isAfilliated Political_Party, :isMemberOf Caucus, :isAppointedTo Organization… Semantically, are they at all different? I don’t think there needs to be a new property for each subclass of Organization.
4. In Popolo, we use gn:Feature instead of schema:Place, because gn:Feature has properties for identifiers (e.g. the numeric code of an electoral district) and for classifications (e.g. “ward”, “province”, etc.), which schema:Place lacks.
5. Why is electoral_domicile snake-case instead of camel-case like others? Same with the class names with underscores.

If you re-use rel: and org: I think your ontology can be much more narrow and focused.

Hope this helps!

James

(To my knowledge, everyone is using Popolo as plain JSON and not taking advantage of any RDF features, so nothing relies on the namespace at the moment.) I chose that namespace because my understanding of the terms for W3C Community Groups is that an identically-named namespace can be made available. However, I haven’t spoken to anyone at W3C about it. So, let this be the start of that discussion! What are the next steps?

I want to be helpful and support the work you/this community is doing as it's clearly valuable but in order to do that, we need to work together.
