Make persistent url at https://w3id.org

[stschiff]

For linked data, we need to have a persistent URL to host our terms.rdf and various schema definitions. For this reason I have provisionally assumed in all schema definitions so far that we'll eventually have such a persistent URL at https://w3id.org/poseidon. This seems to be easy to set up, following the instructions on https://w3id.org, with a redirect on our GitHub page. Later, if we decide to move away from github, perhaps to an MPI-hosted website, we can just change the redirect with w3id.org and don't have to change any of the linked data RDF terms.

So we need to grab https://w3id.org/poseidon and set up that redirect.

OK, I had a look into https://w3id.org and it's pretty straight forward to set up a redirect, but it requires writing an .htaccess file. Does anyone have experience with that?

According to this, it should be as simple as having this .htacess file here https://github.com/perma-id/w3id.org/blob/master/poseidon/.htaccess.

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^$ https://poseidon-framework.github.io [R=302,L]

See example here

But do you understand what all of this means and does? Say, the [R=302,L] clutter?

[maxibor]

302 is the type of redirection (see here), L is for telling Apache to stop looking any further (httpd.apache.org/docs/2.4/rewrite/flags.html)

I opened the PR here

Woohoo, it works. We can now access our terms and schema files like this http://w3id.org/poseidon/terms.rdf.json or http://w3id.org/poseidon/sitesTable-schema.json.

Thanks a lot. That's done.
