New version of PASTA's .eln file

[SteffenBrinckmann]

• include signature using minisign (#56)
• include all metadata as PropertyValue into main json file (see #58)

A few remarks while manually checking the JSON-LD:

• Nested entries like sdPublisher, author, etc. should ideally be flattened and only referenced via their @id.
• Some entries like the author or the flexible metadata are missing a @type.
• Side note: Have we discussed yet whether variableMeasured is the best place for the flexible metadata beyond the initial suggestion?

SampleDB currently fails to import the .eln file as the file ./temporary_pastaTest/StandardOperatingProcedures/SEM.md is referenced, however it does not exist. The temporary_pastaTest directory only contains a file data_hierarchy.json, nothing else.

Aside from that, there seem to be a lot of additional properties there, which I'm not sure whether they are useful to display to a user, e.g. _attachments.v0.json.digest to _attachments.v51.json.digest (and the respetive lengths, revpos, etc). These are also listed for File objects, not just for Dataset objects, which isn't valid.

The example directory README should be updated to reflect the new ro-crate-metadata.json, right?

@nicobrandt I don't think so, but going by schema.org, a Dataset can contain a PropertyValue either as variableMeasured or variablesMeasured, aside from it being used as identifier. variablesMeasured is retired and recommends using variableMeasured, so unless we want to deviate from the existing properties, variableMeasured is the most fitting.

A few remarks from my side:

• As per specification, the folder name should match the name of the archive.
• According to the discussion in #9, the hasPart property in the second object in the @graph, should have only the relative paths of the folders. It should be updated in the specification too.
• Additionally, some folders, for eg: { "@id": "./temporary_pastaTest/Steel/" }, { "@id": "./temporary_pastaTest/SurfaceEvolutionInTribology/" }, are listed in the hasPart but are not present in the archive.
• Furthermore, some of the files referenced in the JSON-LD are missing in the archive.

@SteffenBrinckmann, a few remarks:

• you should run the eln2md script so the PR includes changes to the ro-crate-metadata.json in the diff, and it becomes easier to point things
• instead of using ORCID in the @author node, you should use identifier:

"identifier": "https://orcid.org/0000-0003-3432-2297"

• what is the shasum property? The hashing function name must be mentioned.
• regarding the signature, it's great, I could verify it :+1:

@nicobrandt @jmanideep @FlorianRhiem @NicolasCARPi Thank you all for the feedback: helpful and I will incorporate it in the next version. We have not agreed an all of the "methods" used here and the idea here is not to fix anything. It is meant as a test area for ideas and see if/how they could work. Trying something in code is - in my view - better than theoretical discussions. Once we finally agree on things, then we can write tests for them and ... . Nevertheless, this is just the output of code and that code is easily changed, no hard feelings if we agree on alternative methods.
