You can use a CMIS 1.1 AtomPub client and point it at
If you want to check the AtomPub XML returned using the command line, this can be done using
To do a query you can do:
You should probably pipe this through
tidy if you want a readable output:
The following SOAP endpoints are available:
Note that most SOAP CMIS clients are configured by using just the first URL (the one about RepositoryService), the others are derived from it by changing the suffix.
Authentication is done using Web Services Security (WSS) UsernameToken.
Here is a working example of a SOAP message to the DiscoveryService:
Several free clients for CMIS 1.1 are available.
The best one is the CMIS Workbench, part of OpenCMIS.
And of course you can use the Chemistry libraries to produce your own client (Java, Python, PHP, .NET). Documentation and sample for using OpenCMIS libraries can be found on the OpenCMIS developer wiki with also example code and how-tos.
From Java Code Within a Nuxeo Component
To create, delete or modify documents, folders and relations just use the regular
CoreSession API of Nuxeo. To perform CMISQL queries (for instance to be able to perform
JOIN that are not supported by the default
NXQL query language, have a look at the following entry in the Knowledge Base: How to make CMISQL queries from Nuxeo.
The Nuxeo OpenCMIS connector implements the following capabilities from the specification:
Get descendants supported
Get folder tree supported
|Order By supported||Custom|
|Content stream updates||PWC only|
|Changes||Object IDs only|
Version-specific filing supported
|All versions searchable||Yes|
Inner and outer
|Create property types||No|
|New type settable attributes||None|
The following describes how Nuxeo documents are mapped to CMIS objects and vice versa.
- Only Nuxeo documents including the "dublincore" schema are visible in CMIS.
- Complex properties are not visible in CMIS, as this notion does not exist in CMIS.
- Proxy documents are not visible in CMIS.
- Secondary content streams are not visible as renditions.
- Documents in the Nuxeo trash (those whose
deleted) are not visible in CMIS, unless an explicit query using the
nuxeo:lifecycleStateproperty is done.
This mapping may change to be more comprehensive in future Nuxeo versions.
Nuxeo-Specific System Properties
In addition to the system properties defined in the CMIS specification under the
cmis: prefix, the Nuxeo Platform adds a couple of additional properties under the
Since Nuxeo 5.4.2
nuxeo:isVersion: to distinguish between archived (read-only revision) and live documents (that can be edited);
nuxeo:lifecycleState: to access the life cycle state of a document: by default only document in non
deletedstate will be returned in CMISQL queries unless and explicit
nuxeo:lifecycleStatepredicate is specified in the
WHEREclause of the query;
nuxeo:secondaryObjectTypeIds: makes it possible to access the facets of a document. Those facet can be static (as defined in the type definitions) or dynamic (each document instance can have declared facets);
nuxeo:contentStreamDigest: the low level, MD5 or SHA1 digest of blobs stored in the repository. The algorithm used to compute the digest is dependent on the configuration of the
BinaryManagercomponent of the Nuxeo repository.
nuxeo:secondaryObjectTypeIds are properties that can be queried upon: they can be used in the
WHERE clause of a CMISQL query. This is not yet the case for
nuxeo:contentStreamDigest that can only be read in query results or by introspecting the properties of the
ObjectData description of a document.
Since Nuxeo 5.5
nuxeo:isCheckedIn: for live documents, distinguishes between the checked-in and checked-out state.
cmis:parentIdbut also available on Document objects (which is possible because Nuxeo does not have direct multi-filing).
Since Nuxeo 5.6
nuxeo:pathSegment: the last path segment of the document (
