How can I Update RTC Workitem of Attribute type ”String List” by REST API

This can be done. I have just confirmed.

Here are my steps.
I created a string list in a defect type work item with name MyStringList and added some strings.



1. $ ./curlAuth.sh

This is the content of that script..

COOKIES=./cookies.txt

USER=clmadmin
PASSWORD=clmadmin
HOST="https://<my-ip>:9443/ccm"

curl -k -c $COOKIES "$HOST/authenticated/identity"

curl -k -L -b $COOKIES -c $COOKIES -d j_username=$USER -d j_password=$PASSWORD "$HOST/authenticated/j_security_check"

2. URL=https://<my-ip>:9443/ccm/resource/itemName/com.ibm.team.workitem.WorkItem/2

3. curl -D - -k -b cookies.txt -o "wi-005.json" -H "Content-Type: application/rdf+xml" -H "Accept: application/rdf+xml " -H "OSLC-Core-Version: 2.0" $URL

HTTP/1.1 200 OK
X-Powered-By: Servlet/3.0
x-com-ibm-team-scenario: <some_ip>
ETag: "75720c2a-5be6-3bbf-b137-2490d1ea9f40"
Last-Modified: Thu, 02 Nov 2017 05:19:08 GMT
Cache-Control: private, max-age=0, must-revalidate
Expires: Thu, 02 Nov 2017 05:25:48 GMT
OSLC-Core-Version: 2.0
Vary: Accept, OSLC-Core-Version
Content-Type: application/rdf+xml;charset=UTF-8
Transfer-Encoding: chunked
Date: Thu, 02 Nov 2017 05:25:48 GMT

4. Now open the wi-005.json data and add a line with syntax similar to the other lines:
<rtc_ext:MyStringList rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Cat</rtc_ext:MyStringList>

5. curl -D - -k -b cookies.txt -H "Content-Type: application/rdf+xml" -H "Accept: application/rdf+xml " -H "OSLC-Core-Version: 2.0" -X PUT --data-binary @wi-005.json $URL

6. Refresh the work item and find a new string added to the string list called "Cat". You can add and remove items in the list by adding or removing lines. The rows in the json data come asynchronously, so I don't think it matters exactly which line you add to.

BTW The ETag is not required after all. But for the record, the ETag (entity tag) is defined as "an HTTP response header returned by an HTTP/1.1 compliant web server used to determine change in content at a given URL." It is returned from the REST GET request. It can be used for caching and for conditional requests. There is a little explanation here: http://www.baeldung.com/etags-for-rest-with-spring

Thank you
I will give it a try.

I tried it over and over but I could not acquire the above XML.
String list type is retrieved as a string in json format.
This RTC uses Ver. 5.0.2 ifix 19.

rtc_ext:list_string1がstring list型のデータです。
個々のデータで取 得せず、json型になっています。

Is not there anything to worry about?
