I readily admit that I favor some vocabularies over others when it comes to choosing properties. When it comes to assigning rdf:types, though, I feel much more free to use classes from a variety of vocabularies. In that spirit I would say I am very fond of productontology, without feeling like I have to favor it.

I think we need to make choices amongst the conforming ones. I assume that we will be making some kind of cross-walk from library data to schema.org, and that best practice will be that coded format x (e.g. from the LDR or 007 in MARC) will have a defined value in schema.org that means approximately the same thing. Do we choose "paperback", "mass paperback" or just "book"? It really is a question of what we intend to convey with the schema.org data, what we see it linking to most usefully, what is most accurate, and what is going to be easiest to produce. > > As an example, if you look at that list on WP you see that it has "book series", which is primarily what libraries would call "readers' series" - Harry Potter, "A is for Alibi...," "Narnia", etc. So although it says "series" it isn't the same as what is in an 8XX field. There IS an article for "monographic series". The monographic series article is pretty piss-poor, however, and needs a serious amount of work. Should we use it as is? Does it represent the same concept as the 8XX fields? > > I love WP, I do, but there's a great variation in the quality of the pages. Nothing on WP can be taken at face value - we need to be smart about it, and even pro-active, if we are to take WP links to be *definitional* of our data elements. I'm not comfortable with assuming that any page on WP is by definition authoritative. (I'm in the midst of a huge revision of the DDC pages which were TOTALLY inaccurate, so this is something I'm painfully aware of at the moment.) In addition, we will have to make choices when WP divides the world differently from us. > > Finally, although productontology is available for use, it isn't the only possibility. I know that Jeff favors it, but we need to keep an eye on practice to see if it becomes standard practice, and if it is used by search engines. I hope that some statistics will be available that provide guidance. > > kc > > On 7/5/13 10:57 AM, Corey A Harper wrote: >> Hi Karen, >> >> Can you say a bit more about "I'm not convinced, having looked at some >> of the pages, that WP shares the conceptual model that we'll find in our >> data."?
