A place where we can all critique freely

To All,

Fran, Andy, and I have been brainstorming on my project that I will be working on this summer. Before I progress more into the CMSP Controlled Vocabulary criteria, I have a few questions that I hope can be answered.

1. There are several questions on the Draft Criteria that has several parts within it. Is it suitable to break those down so that we can narrow down exactly what is asked in the question? For example, #7 ask: "Does the vocabulary have a governance structure? Is there a well-documented system for suggesting new terms and have them adopted for the larger community? (Email request to the author/maintainer? Formal committee/ reviewstructure?)"

2. #6 states: "Does the vocabulary make a clean distinction between types and instances?" There seems to be a lot of confusion as to what this entails. Do you want to examine each of their vocabulary terms and see if they make that clear distinction between types and instances? What is a good example of a vocabulary that has a distinction between types and instances? Is there even one?

3. #12 states: "Have one or more science/disciplinary communities approved and/or adopted the vocabulary?" Wouldn't that be similar to mapping/ crosswalks? (#9)

4. A lot of the questions ask if each component is being maintained. Wouldn't that be the same as #3. Different versions allow revisions and updates to be posted and shown to the public.

5. What does it mean when you say, "Are they promoted/ required by the governance structure and terms of use?" (#10)

6. #8: "extensible to new levels" meaning continuing an hierarchical level? That would require a suggestion of a term and then having that term be extensible right?

I think clearing up the uncertainty of the Draft Criteria questions will allow a smoother ride in locating more of these controlled vocabularies. Attached is a copy of the matrix that I have started on in excel. Please add, delete, suggest, comment, etc. I want you to critique, it will only help perfect the process.

0. When I download the vocabulary that's at http://marinemetadata.org/guides/draft-criteria, the draft criteria in it only go up to 9. where's the authoritate list of questions again?  (Should add this to the key links, and a link to it from this page. I saw at the end it's attached, but I can't find it, and that's a little late for my review, sorry!)

1. Yes please, I'd like to see questions broken down.  Combine questions into one if it can be done cleanly, and of course clarifying text is always fine. So in your example #7, the material after the first question is really explanatory text, which should be included. Something like "Does the vocab have a governance structure?  (A good way to determine this is whether there is a well documented system for suggestings new terms -- like emailing a request -- and having them adopted, like via a formal committee and review structure.)"

2. This is a question for a semantic expert to answer. (Both question #6, and your question about question #6.)  if the vocabulary is carefully thought through, you will not find a mix of categories and items in those categories at the same level, for example vehicles - trucks - cars - transportation.  (That's the short form, but I am not a semantic expert. :->)  There are many good vocabularies of this sort, all ontologies for example.  The CF standard names work hard to remain all instances. GCMD is getting there.  The IOOS standard variables are not such a good example.

3. No, I think not. The first is about formal adoption. The second is about usage statistics and practices, and also usability (more crosswalks/mappings = more interoperability).

4. Each different type of component that is maintained (vocabulary, user's guide, mappings, etc.) is a further indication of the maturity of the vocabulary.

5. Can't find the original #10, sorry.

6. It would require a suggestion of a term that is at a lower level, and that can be represented at that lower level.  In a list with cars, trucks, and bicycles, can you add 'pickup truck' and make it clear it is below 'truck' in its level?
