Nuxeo Got Involved Early

2008: Nuxeo joins OASIS to work on the spec

2009: Nuxeo proposes Apache Chemistry project •  5 out of 9 of the original committers are from Nuxeo

2011: Apache Chemistry becomes a top-level project

2013: CMIS 1.1 becomes an OASIS standard

2010: CMIS 1.0 becomes an OASIS standard

Major ECM Vendor Support

CMIS Addresses Interoperability

72% of enterprises have more than one ECM repository…25% have three or more

Let’s Look at Some Code

GOAL: Write Java code that will add a document to a folder that will work when run against any CMIS repository.

#nuxeoCMIS

Grab a Folder

Folder folder = (Folder) session.getObjectByPath(somePath);

Set Up Some Properties

Folder folder = (Folder) session.getObjectByPath(somePath); Map <String, Object> properties = new HashMap<String, Object>(); properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document"); properties.put(PropertyIds.NAME, filename);

Create a ContentStream

Folder folder = (Folder) session.getObjectByPath(somePath); Map <String, Object> properties = new HashMap<String, Object>(); properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document"); properties.put(PropertyIds.NAME, filename); InputStream stream = new ByteArrayInputStream(anArrayOfBytes); ContentStream contentStream = session.getObjectFactory() .createContentStream( filename, Long.valueOf(anArrayOfBytes.length), "text/plain”, stream);

Create a Document

Folder folder = (Folder) session.getObjectByPath(somePath); Map <String, Object> properties = new HashMap<String, Object>(); properties.put(PropertyIds.OBJECT_TYPE_ID, "cmis:document"); properties.put(PropertyIds.NAME, filename); InputStream stream = new ByteArrayInputStream(anArrayOfBytes); ContentStream contentStream = session.getObjectFactory() .createContentStream( filename, Long.valueOf(anArrayOfBytes.length), "text/plain”, stream); Document doc = folder.createDocument( properties, contentStream, VersioningState.MAJOR); System.out.println("Created: " + doc.getId()); System.out.println("Content Length: " + doc.getContentStreamLength());

CMIS Query Language

SELECT cmis:objectId, cmis:name, cmis:description, dc:contributors FROM cmis:document WHERE cmis:name like 'sample%'

SELECT cmis:objectId, cmis:name, cmis:description, dc:contributors FROM cmis:document WHERE CONTAINS('white paper')

Read the Spec

CMIS Specification Home Page https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=cmis

Current Version: CMIS 1.1 Approved: December, 2012

Dealing with Different Repositories

•  Imagine writing an industry specification that must work for repositories that already exist • Challenge:

1. Be flexible enough to support the broad range of functionality in the industry 2. Be descriptive enough to add value as a standard

Nuxeo 7.1 Repository Capabilities

Vendor Info

Capabilities

Root folder ID

Change token

#nuxeoCMIS

Two CMIS Repositories, Differing Capability

Case Management Showcase

• Document capture • Document update • Renditions

#nuxeoCMIS

CMIS in the Real World

• Renditions, renditions, renditions... • Use case: Get all changed documents • Use case: Content migrations

#nuxeoCMIS

Things to Know

• Pay attention to repository capabilities • Cache the CMIS Session • Treat object IDs as opaque • Prefer the browser binding • What you ask for can affect performance •  getDescendants(), getChildren() •  select * from cmis:document• Large documents? •  appendContentStream()• Change tokens
