This presentation shows how the CMIS specification and Apache Chemistry can be used to create content-centric applications that work with any CMIS-compliant repository.

1. Jeff Potts
Apache Chemistry in Action: Using CMIS
and your favorite language to unlock
content from ECM repositories
jeff.potts@alfresco.com OR jpotts@apache.org

2. 80% of the content in an Enterprise is unstructured

3. Managing & collaborating on files is a pain
Jeff Potts jeff.potts@alfresco.com
Where is the latest version?
Who changed it last? What did they change?
Which project is this related to?
Who should be allowed to see this file? To
make changes?
How long do we have to keep this file?
Can I get this file in another format?
I’m done with this file, what happens next?

4. So we write apps that help deal with content

5. But files are a strange beast
Jeff Potts jeff.potts@alfresco.com
Don’t work well as BLOBs in an RDB
– Can’t be indexed
– Can’t be streamed
– Subject to size limitations
File systems alone aren’t rich enough
Neither are Amazon S3 buckets

6. That’s where a content repository comes in

API
Repository
(WebDAV, FTP, etc.)
File Protocols
RDB File System
(Metadata) (Files)
Content Object

7. The Problem: Until now, each repo had its own API

Most organizations have multiple repositories!

8. An industry-wide specification is born: CMIS
Jeff Potts jeff.potts@alfresco.com
Managed by OASIS
Broad vendor support and
adoption
1.0 out now, 1.1 coming soon

9. CMIS specification describes a repo and what’s in it
Jeff Potts jeff.potts@alfresco.com
Domain Model: Repository, Folder,
Document, ACL, Relationship, Object
Type, Secondary Type*, Item*
Binding: Web Services, AtomPub, Browser
(JSON)*
Query Language: Subset of SQL-92
*New in CMIS 1.1

10. Apache Chemistry is the CMIS reference implementation
Jeff Potts jeff.potts@alfresco.com

Client libraries, server frameworks,
development tools

11. Getting started with CMIS
Jeff Potts jeff.potts@alfresco.com
Grab a CMIS client from Apache Chemistry
Find a CMIS-compliant repository
You need its “service URL”
Connect to it with the OpenCMIS
Workbench

12. Let’s see a demo! Python & cmislib, multiple repos
Jeff Potts jeff.potts@alfresco.com
cmislib

13. Let’s see another! Java & OpenCMIS, Servlets & JSPs
Jeff Potts jeff.potts@alfresco.com
The Blend
– An example music mash-
up site
– Java Servlets & JSPs
– Show it running against
multiple CMIS
repositories
– Full source available
from Manning

15. Coming in CMIS 1.1
Jeff Potts jeff.potts@alfresco.com
Browser (JSON) Binding
Type mutability
Secondary types (aka “Aspects”)
Item

16. Thanks!
