 Hello everyone,


we still use the old Doors Web (and also Doors Desktop 9.x) and I need to fetch all requirements via the OSLC API and convert them to JSON.

I already managed to query the requirements I need, but I just cant find a way to identify which XML attributes correspond to which custom field.

My response looks like this

<?xml version="1.0"?>
<rdf:RDF
        xmlns:rm_property="<company_url>/dwa/rm/urn:rational::1-48beda447cfb0c27-M-0000f900/types/">
    <oslc_rm:Requirement
            rdf:about="<about url>">
        <rm_property:attrDef-1049 rdf:parseType="Literal">
            <div>---</div>
        </rm_property:attrDef-1049>
        <rm_property:attrDef-1053 rdf:datatype="http://www.w3.org/2001/XMLSchema#integer"></rm_property:attrDef-1053>
        <rm_property:attrDef-1069
                rdf:resource="<company_url>/dwa/rm/urn:rational::1-48beda447cfb0c27-M-0000f900/types/attrDef-1069#2"/>
        <rm_property:attrDef-1067 rdf:parseType="Literal">
            <div></div>
        </rm_property:attrDef-1067>
        <rm_property:attrDef-1006
                rdf:resource="<company_url>/dwa/rm/urn:rational::1-48beda447cfb0c27-M-0000f900/types/attrDef-1006#9"/>
        <rm_property:attrDef-1078
                rdf:resource="<company_url>/dwa/rm/urn:rational::1-48beda447cfb0c27-M-0000f900/types/attrDef-1078#1"/>
        <rm_property:attrDef-1035 rdf:parseType="Literal">
            <div></div>
        </rm_property:attrDef-1035>
    </oslc_rm:Requirement>
</rdf:RDF>

How would I find what's the corresponding attribute in doors web and the value of that attribute.

When I query the URLs of the rm_property:attrDef-xxxx attributes, I just get a list of my requirements.

Any help is greatly appreciated.

 Have you looked into how OSLC works? Here is the core specification: https://docs.oasis-open-projects.org/oslc-op/core/v3.0/oslc-core.html Provided you pass the correct headers - this is critical, you are supposed to get a result back, where the properties of the OSLC resource are in the result body. Attributes/properties of simple types like string should be in the result. Otherwise the value would be a link to a resource that contains the detail.  Headers are: OSLC-Core-Version: 2.0 Accept: application/rdf+xml Content-Type: application/rdf+xml

 Your XML does not look like RDF+XML.

@rschoon Why does this not look like RDF+XML? What's missing there? That's the (slightly shortened) Data I get from Doors.

I was wrong, pasted XML in this forum is usually hard to read. I was missing the prefixes, but there is a prefix. A better way might be using text/turtle. the attributes are e,g, rm_property:attrDef-1049 and you could get more details using the rdf:resource url.

  That's the strange part. When I grab the URL from lets say rm_property:attrDef-1069 (<company_url>/dwa/rm/urn:rational::1-48beda447cfb0c27-M-0000f900/types/attrDef-1069#2) and query it using the application/rdf+xml headers I just get a long list of URLs back, which looks suspiciously like the list of all requirements instead of the enum values. The response looke like this (but with over 1000 entries) https://pastebin.com/b8HBw40q And if I try to access an OSLC URL with "Accept: text/turtle" header, doors refuses to answer and returns an error code.

 Yes, it looks like you get the uses back. You have to always provide all headers e.g. OSLC-Core-Version Maybe Doors does not support turtle. I have no Doors instance.

With your pastebin response, I think it's working as intended. I think you need to query each one of those responses to get your DOORS objects.

 Thanks for all the help I got.


In the end I found out that you can add "useEnumLabel=true" to the query and get enum labels back instead of links
