Connect MARIS as an ODIS node

[jmckenna]

Background on MARIS:

• home: https://maris.iaea.org/
• does have an API for data: https://maris.iaea.org/api/Search/getsampledata-minimized
• unknown if each record has a landing page (to possibly allow ODIS to harvest its JSON-LD embedded on the landing page for the record)

Background on ODIS:

• see first steps at https://book.odis.org/gettingStarted.html

does have an API for data: https://maris.iaea.org/api/Search/getsampledata-minimized

Seems not to resolve. In our meeting (now), IAEA notes that there's a familiarity needed to navigate their data, but it's very stnadardised)

unknown if each record has a landing page (to possibly allow ODIS to harvest its JSON-LD embedded on the landing page for the record)

Confirmed. May be easier to use a direct link to JSON-LD without a landing page, if MARIS doesn't need such pages. Similar to what ZMT does: https://catalogue.odis.org/view/3289 (see their ODIS-Arch sitemap, which links off to the JSON-LD)

The current implementation bundles the metadata and data together in NetCDF / CSV - the goal would be to open those out such that the metadata is independent (which would assist FAIR alignment)

[jmckenna]

• possibly related script to convert NetCDF metadata into JSON-LD (used to harvest World Ocean Database netcdf files stored on Amazon instance)

FYI schema.org to PROV mapping: #451

• type Dataset JSON-LD template

Here is an example of MARIS dataset metadata

You can also check out the CONFIGS_CDL dictionary here in the global_attrs key.

Note that this is open to modification/improvement. Most of these fields are filledd in by Marisco handlers either from the dataset itself or fetching data from MARIS Zotero records.

Ideally, we'd like to add links to the dataset itself as different format (.csv, .netcdf) or data visualization. For instance we use ObservableHQ for data viz. purpose:

• Official IAEA MARIS account This notebook shows also how to fetch MARIS data from an API endpoint
• This one can give you an idea of what's in MARIS

Note that none of the data vis. above actually uses NetCDF but we do plan to provide them also.
