Vocabulary activity reactivate (or the Ingo's email).

Since last fall, we worked hard on improving the OGC Definition server so that we can register and serve vocabularies easily. We have now deployed the second generation of this service and we would like to load it with vocabularies/terms that you use in your citizen science projects.

Now we need your help, as we need content/examples/vocabularies that you are using. You can provide to Rob, Bart, and myself whatever you have. If you have your resources organized according to SKOS, or you have a CSV file that includes some data, or you simply point us to a web server that serves your data does not matter. All we need is the term, its definition, and who has defined it. The "terms" can be project names, observed properties, observed areas/location names, sensor descriptions, sampling protocols and guidelines,... virtually anything. We just need a sentence providing a definition (can be many sentences as well). If you are aware of an externally provided definition, even better, then we will reference to that one.

The goal is that we make terms (identifiers) de-referenceable (i.e. accessible or readable for both humans and machines) through the definition server. The server has two branches. One is the operational branch, where each term goes through the auspices of the OGC Naming Authority, and the experimental branch, where we can play around as we like. We will use the experimental branch for now, but nothing prevents us from moving resources from the experimental to the operational branch once stabilized.

The overall motivation is that consumers have a "reference of truth" for each term. Normally, if you go to a data server and request e.g. air pollution data for your home town, you get some data together with usually very brief and sometimes cryptic identifiers, e.g. observedProperties: aTemp, PM10, NOx, sensor: SDS011. So what do these things mean? By having a URL that can be accessed, you find out that "aTemp" stands for air temperature, or that SDS011 is a high precision laser pm2.5 air quality detection sensor module.

Some further information can be found on the wiki page "publishing Interoperability Resources as Definitions" at http://external.opengeospatial.org/twiki_public/CitSciIE/PublishingDefs, but in principle this email should contain all information you need.

Please don't hesitate to contact Rob, Bart or myself if you have any further questions!

Ingo

And remember - these terms could be just column names in CSV files or any other place where the user might need to understand exactly what is meant, because short names are always ambiguous. I can help extracting these into a standard format (SKOS) but need the samples and some definitions.

Reporting and discussion

• For each of you attending be ready to report on the following questions:
  • What have you done in the last month? (relate that to the working items identifiers).
  • Are you able to provide a demo for today or the telecons to come?
  • What do you need from other participants
  • What you could do in the next month.
