Hello!
Is any way to get text data for Rational DOORs Next Generation text artifact with OSLC or Reportable API?
I was trying to get history of an artifact with: 
https://<server>:9443/rm/publish/resources?resourceURI=_HlSQwb_UEeegWoVqUPnDvQ&history=true
It gives a history of entries with such data as: 
<history:oldValue type="url">
https://<server>:9443/rm/resources/_ItKe0b_UEeegWoVqUPnDvQ?revision=_IteA0b_UEeegWoVqUPnDvQ
</history:oldValue>
<history:value type="url">
https://<server>:9443/rm/resources/_JtU7Ub_UEeegWoVqUPnDvQ?revision=_JthIkb_UEeegWoVqUPnDvQ
</history:value>
But I can not get text content with these values from an external program.
If I do a request for revisions: 
https://<server>:9443/rm/resources/_Esg9wb_dEeegWoVqUPnDvQ?revisions
So I can not find text data there.
May be somebody realized the same ever. If it's available, can somebody give a little advice how to do it correctly? If not possible, so could you confirm it? 
My question is made after investigating of other questions:
But I can not find there clear answer to my question!
Thank you very much in advance!

I realize this is a 2 year old thread, but I am encountering the same issue as Dmitry.  I want to retrieve the oldValue and value fields.  However, the provided URLs (when retrieved) are a bunch of Javascript and not the content I'm after.  It looks like it's meant for a web user interface and not to be machine readable.

Is there a solution to this or are we stuck, unable to get the history values?

I'm on Doors NG 6.0.6.1 and I have written a Python program that retrieves all of my system requirements, and one analysis I want to do is to detect when a user changes a particular field of a requirement.  I can tell when the Primary Text was altered, but I can't get the actual text that changed via my Python code.  I got so close to the solution but now I'm stuck!

Hi Dmitry,

I think your best bet is using the "history" parameter as described in one of the other posts you mentioned.  This ends up using the reportable REST API, for example:

https://<server>:<port>/rm/publish/resources?resourceURI=_UCe30MABEeeW25QDs6YRwQ&history=true

Hi Benjamin,

Thank you for quick answer! But the problem is that I applied this parameter, and I can not extract text data from the response's data. The response returns such attributes as:

<history:oldValue type="url">
<history:value type="url">

But I don't know how extract their values with a typical GET request. I can only input them in address field of a browser and open the related web page but not more.
