(In)compatibility with certain ro-crate-metadata.json file

[gcapes]

I'm new to RO crates and have installed ro-crate-html-js, trying to build an html preview page.

I have had success with a minimal ro-crate-metadata.json example, but I get errors when trying a different file @stain , which I believe was previously build without issue using your tool.

$ node_modules/.bin/rochtml ro-crate-metadata.json

Would you be able to look into this?

Thanks!

You can get this working if you remove "https://schema.org/" from line 4 of the source file (it should not be needed, as the RO-Crate context has Schema.org in it anyway - I think Schema.org changed the way they serve the context file so this no longer works (is that right @stain?). The code should not be dying like this, though so I will ask @alvinsw to look at this issue and make sure that we fix it.

Note that development on this is now taking place over at https://github.com/Arkisto-Platform/ro-crate-html-js - we need to make sure the RO-Crate site is pointing to the right pkace.

@simon-kruik - would you be able to put a notice on the UTS repositories to say that they have moved?

Pull request #25 has been created for this repo with an updated README. Did you also want a similar notice on https://github.com/UTS-eResearch/ro-crate-js and https://github.com/UTS-eResearch/ro-crate-excel @ptsefton?
