Hi all,

Here is some feedback on our Use Cases from the catalogue manager of the Australian National Data Services.

Hi Nick,

Thank you for passing this on to me.  It's great to see this initiative and its apparent support and momentum.

That is quite a list of use cases.  The items that occur most frequently to us appear to be addressed, for examples, things like:

- sufficient and sufficiently granular citation information

- ability to discover resources by funder or grant (consider purls for Activity records within the RDA Activity Portal)

- resource types expanded to include software etc, taking guidance from existing vocabs

- ability to connect to provenance information, so that where it exists, use-cases can be satisfied by interrogation of the prov rather than being limited by the extent of population of the DCAT - for example, the use-case of seeking which datasets are derived from a particular dataset can be satisfied by analysing the provenance info linked to the particular dataset's description.

- sufficient information regarding service protocol and specific service function within distribution URL, e.g. 'OGC WMS' 'data-access'; or 'CustomAPI' 'data-access' and ability to link to CustomAPI documentation and or include enough parameter information for immediate use of the service.

There will certainly be things that occur to us as time goes on and as we see to what extent requirements are addressed.

Melanie

Hi Melanie,

The W3C’s Data Exchange Working Group (https://www.w3.org/2017/dxwg/wiki/Main_Page) has established a list of Use Cases and Requirements that will dictate what issues relating to data exchange metadata and mechanisms they investigate over the next 18 months. The initial list of Use Cases and Requirements is at https://w3c.github.io/dxwg/ucr/.


The WG’s outputs will enhance the way semantic descriptions of dataset’s metadata and metadata access are made and used and will use things like the basic DCAT dataset vocabulary (https://www.w3.org/TR/vocab-dcat/) as well as the Australian Dataset Ontology (https://data.gov.au/dataset/data-gov-au-dataset-ontology) as starting points. The WG will likely harmonise patterns for both use and extension so we should get both better metadata models and also better mechanisms for profiling them. I hope that this work will also bring Semantic Web and ISO19115-style metadata models closer together, which is where this work will become particularly relevant to ANDS. Perhaps the next version of the ISO19115 standard (2019) will use this WG’s outputs and profiles of that next version, such as GA’s profile, will be implemented using the profiling mechanisms developed by this WG.

I invite you to review the Use Case list and provide any comments you might have to me or to the WG directly. Australia has a strong presence in the WG (me, Rob Atkinson, Simon Cox & Armin Haller) so some perception of ANDS’ needs will definitely be catered for but direct feedback would be welcome!

Thanks,

Nick
