Harvest ESRI Open Data via DCAT

[jamessewell]

I've done some searching - but I don't think this is directly possible at the moment.

ESRI open data provides a data.json file in the DCAT format. Other solutions like CKAN are capable of using this for harvest.

An example: https://vicroadsopendata-vicroadsmaps.opendata.arcgis.com/data.json

Cheers,

An option would be to use something like #4034 but needs some more work.

See also the harvester for the DCAT-AP schema plugin https://github.com/metadata101/dcat-ap1.1

Because it uses Apache Jena to read the RDF, it can deal with several RDF syntaxes: json-lod, rdf/xml, ttl, etc.

Currently, the harvester inserts metadata as DCAT-AP RDF-XML, but you can also make it work for other schemas like ISO19139. Basically, you will need to write an XSLT similar to this one rdf-to-xml.xsl and a Java Harvester similar to this one.
