Adding BCO-DMO specific metadata to datapackage.json #1

@adyork let's review at some point |
|
Hi @ashepherd & @adyork! We are starting to check out this issue and are wondering if there are specific pain points here that you need help with? Or is this issue more documentation for the goal of eventually adding this metadata during the pilot? Thanks in advance for any clarification :-) |

Hi @lwinfree! Maybe just discussion about OKF plans for adding JSON-LD support? If it was of interest and OKF wanted help, I'd be happy to help! I just want to make sure we aren't doing anything that conflicts with OKF plans by using JSON-LD, or if there weren't plans to add support, maybe our office rethinks using it here in favor of inserting a property at the top-level of the JSON that won't ever conflict with OKF future plans. Something like where we insert Overall, our preference would be for JSON-LD support so that both sets of information can live side-by-side without having to duplicate content (re: Frictionlessdata Example: {

@ashepherd Do you feel like it's okay to close this issue given our decision to add custom metadata in the datapackage.json by prefixing with |

Yeah, feel free to close it

PROPOSAL
If adding JSON-LD support is of interest (frictionlessdata/specs#218), define a namespace within
frictionlessdata.iodomain for potentially serving machine-readable descriptions of Frictionlessdata classes and properties. (NOTE: not required)Include an
@contextat the start of any datapackage.json:We use the
@vocabto specify that all the terms in the JSON document are defined in the JSON-LD context provided athttp://schema.frictionlessdata.io/v1.0/data-package/odo,unitsandparamdefines other RDF vocabularies that will be used to define non-default terms in the document.resourcesis redefined from the default vocabulary to a term in theodovocabulary where its scoped propertyfieldsis also defined to be in theodovocabulary. This technique saves time from having to duplicating the same value twice in two different fields. Effectively, it means thatresourcesshould be interpreted as both 1)resourcesfrom the@vocabschema, and 2) asodo:storesValuesForfrom theodoschema.For a full example we modify the frictionlessdata:example-data-packages/periodic-table below:
{ "@context": { "@vocab": "http://schema.frictionlessdata.io/v1.0/data-package/", "odo": "http://ocean-data.org/schema/", "units": "http://vocab.nerc.ac.uk/collection/P06/current/", "param": "http://vocab.nerc.ac.uk/collection/P01/current/", "resources": { "@id": "odo:dataFile", "@context": { "fields": { "@id": "odo:storesValuesFor" } } } }, "name": "period-table", "title": "Periodic Table", "profile": "tabular-data-package", "licenses": [{ "id": "CC0-1.0", "title": "CC0 1.0", "url": "https://creativecommons.org/publicdomain/zero/1.0/" }], "resources": [{ "@type": "odo:DataFile", "path": "data.csv", "name": "data", "profile": "tabular-data-resource", "format": "csv", "mediatype": "text/csv", "encoding": "UTF-8", "schema": { "fields": [{ "name": "atomic number", "type": "integer", "format": "default" }, { "name": "symbol", "type": "string", "format": "default", "odo:unitOfMeasure": { "@id": "units:UUUU" } }, { "name": "name", "type": "string", "format": "default" }, { "@type": "param:TTPBKG01", "name": "atomic mass", "type": "number", "format": "default", "odo:unitOfMeasure": { "@type": "odo:UnitOfMeasure", "odo:title": "Daltons", "odo:unitSymbol": "Da" } }, { "name": "metal or nonmetal?", "type": "string", "format": "default" } ] } }] }To see the RDF triples resulting from this JSON-LD, go to the JSON-LD Playground:
Options > Processing ModetoJSON-LD 1.1
2. Paste the above JSON-LD into the textarea found at the `JSON-LD Input` tab 3. Click the `Table` tab below the `JSON-LD Input`Using this method, we can expand the datapackage.json, using RDF vocabulary terms to describe our Dataset's funding awards, projects, authors and contributors, deployments, parameters, instruments, supplemental documents, related publications, etc.
