First Time Connecting to CRM OData

Which version of OData does the CRM API utilize?

With which address do we attempt to download the Service Document to get descriptive information on the Collections available in the instance? 

https://<orgname>.api.crm.dynamics.com/api/data/v8.0/

...or the Discovery Service?...

https://disco.crm.dynamics.com/api/discovery/v8.0/

Is this truly OData or just 4 disparate CRUD calls via REST?

Would love to RTFM, but may we ask to have someone point us to which manual, which code example, which "recipe" will prove feasibility of our not-often-used-with-OData dev tool in the shortest time?

There's a wealth of information here, but would like to prove connectivity is possible before spending 1+ days reading all the associated documentation.

Thank you very much.

    Which version of OData does the CRM API v2011 utilize?

    I believe it utilizes 2.0 version.

    To All:

    Downloading the OData Metadata from our Customization Developer Resources page results in a file named "ODataV4Metadata.xml" which in its header contains "...<edmx:Edmx Version="4.0" xmlns:edmx="docs.oasis-open.org/.../edmx&quot;>..."

    Does this indicate OData v4 being implemented?

    Thank you.

    To JohnStrano:

    If you are talking about https://<orgname>.api.crm.dynamics.com/api/data/v8.0/ then answer - this endpoint implements OData 4.0

    If you are talking about https://<orgname>.api.crm.dynamics.com/XrmServices/2011/OrganizationData.svc - then 2.0

    You mentioned "Which version of OData does the CRM API v2011 utilize?" so I assumed that you meant old-style OrganizationData.svc which implements Odata 2.0

    Interesting.

    The entry for Endpoint Address  on the Developer Resources page...

    https://<org>.api.crm.dynamics.com/XRMServices/2011/Organization.svc

    "...Organization.svc" not "...OrganizationData.svc"

    ...cites this as SOAP rather than REST/OData.

    If "...OrganizationData.svc" is for OData V2 (please confirm), it would have been more than helpful for that to be cited explicitly on the Resource page.

    Does MS offer an avenue for enhancement requests for Developer Resources?

    I'm using POSTMAN to issue the GETs for...

    https://<org>.api.crm.dynamics.com/XRMServices/2011/OrganizationData.svc/

    I'm seeing a boatload of style data as well as substantial javascript.

    Is there a call/URI/endpoint that will return only the XML...well-formed?

    No DTD, no schema?

    Thank you.
