You can use VersionService API to get version document's content. This Interface have many method like createVersion, deleteVersion, currentVersion.

Hi,
I have a requirement where I have to retrieve a specific version which may not be the latest version. How do we retrieve the versions which are not the latest versions? The noderef is always point to the latest version. Do we have any node id available for each version?

Thanks,
Naveen.

It depends on what api are you using. java foundation api? javascript api ? webscript api? cmis api ?

Hi Kaynezhang,

We are using web scripts.

Thanks,
Naveen.

You can use folloing webscript api

GET /alfresco/service/api/node/content{property}/{store_type}/{store_id}/{id}?a={attach?}&streamId={streamId?}
GET /alfresco/service/api/path/content{property}/{store_type}/{store_id}/{nodepath}?a={attach?}&streamId={streamId?}
GET /alfresco/service/api/node/{store_type}/{store_id}/{id}/content{property}?a={attach?}&streamId={streamId?}
GET /alfresco/service/api/path/{store_type}/{store_id}/{nodepath}/content{property}?a={attach?}&streamId={streamId?}
‍‍‍‍‍‍‍

rememeber you should use your store_id is version2Store
for example

      String uid = "fa6237f1-5925-4e69-98ad-9731492c2d3f";
      String apiurl = "http://localhost:8080/alfresco/service/api/node/workspace/version2Store/'+uid+'/content";

Hi Kaynezhang,

Thanks for your info. My last query is how do I capture the uid of the document? The UUID is same for all the versions but is there any property which can specify the version specific id.

Thanks,
Naveen.

Use following webscript api to get all versions for a node, parse the returned xml you'll get a specified version uid.

GET /alfresco/service/api/node/{store_type}/{store_id}/{id}/versions?filter={filter?}&includeAllowableActions={includeAllowableActions?}
GET /alfresco/service/api/path/{store_type}/{store_id}/{nodepath}/versions?filter={filter?}&includeAllowableActions={includeAllowableActions?}
‍‍‍‍

for example

      String uid = "1565a32e-7863-45af-a9fa-b68ad206b5e7";
      String apiurl = "http://localhost:8080/alfresco/service/api/node/workspace/SpacesStore/'+uid+'/versions";
