Hi,

I want to fetch all requirements that exists in a folder using OSLC and tried it by using the RESTClient.

I have added &oslc.prefix=nav=<http://jazz.net/ns/rm/navigation#>&nav:parent="

Hi,

Try following query :
" &oslc.prefix=nav=<http://com.ibm.rdm/navigation%23>&oslc.select=*&oslc.where=nav:parent=<YOUR_FOLDER_URL> "

Where your folder URL may looks like : "https://grarrc.ibm.com:9443/rm/folders/_RHCJYN5jEeGb6IIbvOh9Dw"
NOTE: On the query does not use the beginning and ending " chars

Hi,

Sorry, but that did not help.

So now I wonder if someone can tell me which is the best way to getting all the requirements in a folder using OSLC?
I got the folder name and are able to retrieve the uri to the folder.

Could you attach the query your are using?

Cecilia Lindgren commented Oct 11 '12, 10:12 a.m.

https://server:9443/rm/views?oslc.query=true&amp;projectURL=https%3A%2F%2Fserver%3A9443%2Fjts%2Fprocess%2Fproject-areas%2F_xdjJsP2cEeGoOoZWLhSJmQ&oslc.prefix=nav=<http://jazz.net/ns/rm/navigation#>&oslc.where=nav:parent=https://server:9443/rm/folders/_-0W0x_5KEeGoOoZWLhSJmQ&oslc.select=*

the value of the nav prefix is fetched from the response.

What is the best way to fetch the requirements for a folder?
From query base for requirements, from query base for folders or something complete different?
Am I missing any headers in my request?

Cecilia,

Good article, but it does not solve the issue about fetching requirements for a spcific folder.

Hi Cecilia,

I encoded the # character in the nav ns using UTF-8 and removed the amp after &. Can you please try this:

https://server:9443/rm/views?oslc.query=true&projectURL=https%3A%2F%2Fserver%3A9443%2Fjts%2Fprocess%2Fproject-areas%2F_xdjJsP2cEeGoOoZWLhSJmQ&oslc.prefix=nav=<http://jazz.net/ns/rm/navigation%23>&oslc.where=nav:parent=https://server:9443/rm/folders/_-0W0x_5KEeGoOoZWLhSJmQ&oslc.select=*

 After attempting several variations I was (mostly) able to do this.   The root problem is that I could find no way to get RRC 4.0.1 to accept an oslc.prefix that used the <http://jazz.net/ns/rm/navigation#> namespace.   I think there is a bug here, but wanted to see if anyone sees a better solution.

First,  I am putting all URLs/query strings un-encoded in this post for readability in these examples.  In reality I was encoding them correctly.

1.  Do a GET on a Requirement with OSLC-Core-Version=2.0 and Accept = application/rdf+xml.   In part it returns:
snip...
xmlns:nav="http://jazz.net/ns/rm/navigation#"
...snip 
<nav:parent rdf:resource="https://server:9443/rm/folders/_jJkdxjJVEeKUCMIZfXk1OA"/>
2. I want to do a query for all requirements in that same folder. This query (properly encoded), does not work
oslc.prefix=nav=<http://jazz.net/ns/rm/navigation#>&oslc.where=nav:parent=<https://server:9443/rm/folders/_jJkdxjJVEeKUCMIZfXk1OA>
There is a SPARQL error and the namespace is not properly escaped with &lt; &gt; in the SPARQL in the RRC log.
3. This query DOES work (note the namespace which does not match the one on the GET in step 1):
oslc.prefix=nav=<http://com.ibm.rdm/navigation#>&oslc.where=nav:parent=<https://server:9443/rm/folders/_jJkdxjJVEeKUCMIZfXk1OA>
This looks like a "legacy" RRC namespace.
The nav namespace on the original GET should be the one I can use on the query, but in this case I could only get it working using the "alternate" namespace. Does anyone have a better approach?

Hi Mike,
It seems to be an issue in 4.0.1 I have opened a wi to fix that. As you mentioned, the workaround is to use the old namespace.

Hi, i know that this is a very old question, but i have the same problem with this query. 
I tried to use both namespaces, but none of them works. 
I use the RM in version 5.0.2.
My sample queries (i encode them, because when i  paste the address, format was not readable. Please to read use something to decode, for example this page)

https%3A%2F%2F%5Bserwer%5D%3A9443%2Frm%2Fviews%3Foslc.query%3Dtrue%26projectURL%3Dhttps%3A%2F%2F%5Bserwer%5D%3A9443%2Frm%2Fprocess%2Fproject-areas%2F_lSxTMu7LEeW7ncSEDSVoCA%26oslc.prefix%3Dnav%3D%3Chttp%3A%2F%2Fjazz.net%2Fns%2Frm%2Fnavigation%23%3E%26oslc.where%3Dnav%3Aparent%3D%3Chttps%3A%2F%2F%5Bserwer%5D%3A9443%2Frm%2Ffolders%2F_7oeNsfDrEeW7ncSEDSVoCA%3E

My goal is to display all requirements that are located in the specified folder. Is something has changed between versions 4.0.1 and 6.0.1 with regard to this topic ?
