update GDAL service context product

[sarabond]

Update the GDAL context product as well as creating a new context product for gdal3.js.

[sophiaconover]

Sara will add internal references the context products. File names should be lowercase and have the version number, for example, gdal3_1.0.xml

@sarabond any updates on this PR?

[jordanpadams]

@sarabond ping! :-)

Hi @jordanpadams, I'm waiting for input from @rgdeen on what the GDAL references should point to. Once I have that information, I can complete this task.

Hmm - actually I'm not sure I know what this means. Do you mean some example archive GDAL supports like "lroc"?

<Internal_Reference>
    <lid_reference>urn:nasa:pds:context:instrument:lro.lroc</lid_reference>
    <reference_type>collection_to_instrument</reference_type>
</Internal_Reference> 

GDAL is really better at derived data (RDRs). Should we point to just to the LROC RDRs?
https://doi.org/10.17189/a6a1-mw73 (urn:nasa:pds:lro-l-lroc-5-rdr::3.0)
or

<Internal_Reference>
   <lid_reference>urn:nasa:pds:lro-l-lroc-5-rdr</lid_reference>
   <reference_type>collection_to_bundle</reference_type>
</Internal_Reference>

We could this for CTX, HiRISE, Magellan, Cassini radar almost anything derived (map projected) and any target body.

BTW, GDAL does have a DOI: https://doi.org/10.5281/zenodo.5884351

Maybe, but it is also useful for just converting .IMGs to anything else, so maybe it is really all camera instruments (and their associated instrument hosts/investigations)?

[rgdeen]

@thareUSGS apparently we have to make a list. But RDRs count... I mean, if someone wants to process LROC data then GDAL should come up regardless of whether they're looking at EDRs or RDRs. I think eventually, we'll be able to have more nuance here, but basically as a starting point we just want to make sure it shows up on appropriate searches.

[sarabond]

Hi all, to clarify the actions here, it sounds like we want searches for instruments/investigations related to LROC data to point to to GDAL, as a start. Correct me if I'm misunderstanding that. If that is the case, I see some resources here that help me to understand the associated camera instruments. Let me know if this is an appropriate resource.
