Examples

There’s nothing in cmislib that is specific to any particular vendor. Once you give it your CMIS provider’s service URL and some credentials, it figures out where to go from there.

Let’s look at some examples using Alfresco’s public CMIS repository.

Get a Repository object

1. From the command-line, start the Python shell by typing python then hit enter.

2. Import the CmisClient:

   >>> from cmislib import CmisClient
   

3. Point the CmisClient at the repository’s service URL

   >>> client = CmisClient('http://cmis.alfresco.com/cmisatom', 'admin', 'admin')
   

4. Get the default repository for the service

   >>> repo = client.defaultRepository
   >>> repo.id
   u'83beb297-a6fa-4ac5-844b-98c871c0eea9'
   

5. Get the repository’s properties. This for-loop spits out everything cmislib knows about the repo.

   >>> repo.name
   u'Main Repository'
   >>> info = repo.info
   >>> for k,v in info.items():
       ...     print "%s:%s" % (k,v)
       ...
       cmisSpecificationTitle:Version 1.0 Committee Draft 04
       cmisVersionSupported:1.0
       repositoryDescription:None
       productVersion:3.2.0 (r2 2440)
       rootFolderId:workspace://SpacesStore/aa1ecedf-9551-49c5-831a-0502bb43f348
       repositoryId:83beb297-a6fa-4ac5-844b-98c871c0eea9
       repositoryName:Main Repository
       vendorName:Alfresco
       productName:Alfresco Repository (Community)
   

Folders & Documents

Once you’ve got the Repository object you can start working with folders.

1. Create a new folder in the root. You should name yours something unique.

   >>> root = repo.rootFolder
   >>> someFolder = root.createFolder('someFolder')
   >>> someFolder.id
   u'workspace://SpacesStore/91f344ef-84e7-43d8-b379-959c0be7e8fc'
   

2. Then, you can create some content:

   >>> someFile = open('test.txt', 'r')
   >>> someDoc = someFolder.createDocument('Test Document', contentFile=someFile)
   

3. And, if you want, you can dump the properties of the newly-created document (this is a partial list):

   >>> props = someDoc.properties
   >>> for k,v in props.items():
   ...     print '%s:%s' % (k,v)
   ...
   cmis:contentStreamMimeType:text/plain
   cmis:creationDate:2009-12-18T10:59:26.667-06:00
   cmis:baseTypeId:cmis:document
   cmis:isLatestMajorVersion:false
   cmis:isImmutable:false
   cmis:isMajorVersion:false
   cmis:objectId:workspace://SpacesStore/2cf36ad5-92b0-4731-94a4-9f3fef25b479
   

Searching For & Retrieving Objects

There are several different ways to grab an object:

• You can run a CMIS query
• You can ask the repository to give you one for a specific path or object ID
• You can traverse the repository using a folder’s children and/or descendants

1. Let’s find the doc we just created with a full-text search.

   Note

   Note that I’m currently seeing a problem with Alfresco in which the CMIS service returns one less result than what’s really there):

   >>> results = repo.query("select * from cmis:document where contains('test')")
   >>> for result in results:
   ...     print result.name
   ...
   Test Document2
   example test script.js
   

2. Alternatively, you can also get objects by their path, like this:

   >>> someDoc = repo.getObjectByPath('/someFolder/Test Document')
   >>> someDoc.id
   u'workspace://SpacesStore/2cf36ad5-92b0-4731-94a4-9f3fef25b479'
   

3. Or their object ID, like this:

   >>> someDoc = repo.getObject('workspace://SpacesStore/2cf36ad5-92b0-4731-94a4-9f3fef25b479')
   >>> someDoc.name
   u'Test Document'
   

4. Folder objects have getChildren() and getDescendants() methods that will return a list of CmisObject objects:

   >>> children= someFolder.getChildren()
   >>> for child in children:
   ...     print child.name
   ...
   Test Document
   Test Document2
