community group.
<danbri> Guha intro
Guha: Looked at proposal. Meta
comments. Learned a few things in the last few years.
Appreciate your trying to clean up healthcare vocab.
... Make sure someone who uses it is signed up. Once you have
the app you'll have publishers.
... When you start with a smallish vocab (10-15 terms) and get
people using it, then it's easy to expand. Starting with 100
terms hasn't worked.
... Anything more than 10-15 terms will make it hard to
convince everyone to use it.
... For explaining it to potential users, much easier if you do
it in small pieces.

<Marc_Twagirumukiza> https://www.w3.org/community/schemed/wiki/Commitments_and_requirements
<danbri> regarding "(MUST) The working format for this community is RDFa." … I assume this is just practicalities / pragmatics, i.e. using the RDFa/RDFS format for compatibility with the schema.org site infrastructure
David: Why RDFa?
Dan: schema.org site is powered by RDFa files that encode a flavor of RDFS that fits schema.org . Therefore we'll use RDFa to be compatible with the way schema.org .
David: Excellent, thanks.
<Marc_Twagirumukiza> https://www.w3.org/community/schemed/wiki/Domestic_standards_of_procedures
marc: To add a property or class,
you need to raise it by an issue on github, then it needs to
have 5 supporters (votes), and then it will be discussed to be
added.
... comments on procedures?
dan: It's in the W3C style, but
not precisely W3C process. We can be faster and more
agile.
... Let's not be overly legalistic and slow.
... Sorry it's taken us so long to connect with you. Guha's
approach would be healthy: start small and go from there.
<David_Portnoy> Agreed. We should start with the lightest governance and methodology possible, until / unless it needs to be more complex and formal.
github repo: https://github.com/twamarc/ScheMed/tree/master/deploys/sdo-schemed
marc: In 2007 HL7 v3 RIM was
made, but it was too big and we failed to implement it.
... Then schema.org came. I think it can play a big role
between systems.
... When I looked at existing schema.org vocab, it was quite
good, but some predicates were missing, and some not placed
right.
... Today i'd like to invite you to look at the proposal in
github (linked above) in RDFa files.
<rjw> http://health.sdo-schemedex.appspot.com/Diagnosis
marc: The readable version is linked above.
richard: That's a working prototype based on Marc's proposal. If adopted, this is what it would look like.
<danbri> Q: is the health extension considered appropriate for markup of clinical trials datasets / reports? e.g. per http://www.alltrials.net/find-out-more/all-trials/
dan: re Clinical Trials data, do you consider the schemas adequate for them? Looking for use cases of a consumer of this data.
marc: Not yet optimized for
clinical trials.
... I think we need to add extra predicates mainly.
michel: I have parsed the clinicaltrials.gov data into RDF, so I have a pretty good idea of that schema. i could assess whehter this is adequate.
dan: We're not sure what schema.org is good for, what's in the center. I don't yet have the data to advocate for this with yahoo and bing, etc.
marc: We have a couple of use
case from the first project.
... Modeled around 16 medical entities
... Missing predicates and items. This model is being used in
Lombardi Italy hospital. And 3 hospitals in Dresden. Belgium
used by Agfa. Switzerland used by ROCHE.
<David_Portnoy> Do we have a location where we're describing the specific use cases that are driving the schema proposals?
marc: But they're not really public.
dan: Use cases are medical informatics, private sharing, and using schema.org as lightweight ont, but not yet using the public web?
marc: Yes.
michel: We're working w much more
public data. Eg, daily med from FDA, or adverse events from
FDA.
... Could find a smattering of data sets that we can expose
using this vocab.
dan: labeling is the topic of GS1 group focus on nutrition, packaged foods of all kinds. If we could bridge those it would be good.
<Sajjad_> For example, the property affectedBy pointed at http://health.sdo-schemedex.appspot.com/affectedBy, where the Canonical URL: http://schema.org/affectedBy. Shouldn't it be more appropriate to have a base URL with namespace http://health.schema.org/ instead of http://schema.org/ ?
dan: You also have a medical term
abortion, but probably don't want to put that on a web
page.
... Need to draw attention back to the public use cases.
sajjad: the property affectedBy pointed at http://health.sdo-schemedex.appspot.com/affectedBy, where the Canonical URL: http://schema.org/affectedBy. Shouldn't it be more appropriate to have a base URL with namespace http://health.schema.org/ instead of http://schema.org/ ?
dan: Let's take this to github.
Several issues: namespaces; general phrases for specific
healthcare uses.
... Previsouly we either used one meaning, and other times we
made a specific def for a particular extension. 'Recipe' must
be usable by anything. Both a strength and weakness.
<danbri> look at http://schema.org/Recipe
sajjad: affectedBy looks like it was made only for med domain.
<danbri> in Recipe we have effectively pseudo-namespaced various otherwise-general terms, e.g. 'recipeCategory', 'recipeIngredient' etc.
<michel> +q
marc: We have some predicates that are generic. Need to discuss one by one. Please read the list of all predicates and mark the ones you think are too generic to stay in core, and what should be in extensions.
<Marc_Twagirumukiza> in Google docs: https://drive.google.com/file/d/0B3XqWCPGZuTeRkRBelJxOVJEcWc/view
michel: Re utility for the vocab, do you have an association between the predicates and the use cases, so we know which are used with which use cases?
<danbri> any actions arising from all this?
marc: meeting frequency?
dan: Monthly
<scribe> ACTION: Michel to assess suitability of vocab for clinicaltrials.gov data [recorded in http://www.w3.org/2015/08/28-schemed-minutes.html#action01]
richard: What would be the minimum set of terms needed?
marc: Let's discuss that next meeting.
<Marc_Twagirumukiza> Next meeting: 25/sep
dan: Please have one issue in the tracker for each thing that needs to be discussed.
<scribe> ACTION: Dan to contact alltrials people [recorded in http://www.w3.org/2015/08/28-schemed-minutes.html#action02]
<David_Portnoy> Proposing meeting approach´: Monthly meetings on general, high-level and meta concepts only. In between, GitHub issue discussions on specific schemas, vocabs and topics. Participants can schedule smaller calls just with interested participants from Github on these topics in between.
<scribe> ACTION: Marc to put all questions as issues on github [recorded in http://www.w3.org/2015/08/28-schemed-minutes.html#action03]
