Sorry for the very late reply, Melanie.

The old hand-hacked crawler will be too slow - I finally realized this myself through trying to crawl Biosamples.  Ankit 
(our GSoC student) is working on a much faster Scrapy-based crawler, and Ricardo has GoCrawlIt.  We're now all working 
under the Buzzbang umbrella to have these scrapers deposit to a common format in MongoDB.  More details through the 
links at [1].

When you guys have any questions, please feel free to pop over to the Bioschemas Buzzbang channel at [2] or of course, 
create an issue on the appropriate Github.  This is all skunkworks still, Ankit's GSoC programme will end in August and 
myself and Ricardo are only unofficially working on this, but it will be great to see some real-world issues.  We hope 
to deploy the newer scrapers to Cambridge HPC cloud soon, after which a common crawl will hopefully become available 
down the line.

I understand defined terms to be a mechanism to provide a finite list of terms to be used in our profiles - which is why I thought they’d be a good way to define “protein” “samples” “gene” etc - the 20 or so entities we are using throughout. I don’t think they’d be suitable for a list of unknown terms as we obviously wouldn’t want to have a dictionary of millions of terms (in addition to them already being hosted by OLS for example)

We have deployed the bioschemas markup on the BioSamples samples, and are now adding a context to link the sample entity to the corresponding OBI term - similar to what was done for protein and PRO. It seems to be working fine at the moment.

If Samples mark up is already in use and tools are working fine with CategoryCode, I guess it would be better to stick to it.
