CMIS

The CMIS specification is a well-written and easy-to-read document, but some things are still left open to interpretation.

Folders in a CMIS repository form a strict hierarchy, in which a folder can be contained only within a single parent folder.

Please always test with at least two compliant repositories to make sure that you are Oasis CMIS specification compliant.

It's possible (as a CMIS repository option) to allow documents to be contained in multiple folders or even in no folders at all.

Being restful, all of its services are accessed through URL, but the CMIS specification leaves the specific URLs up to each vendor.

In the case of CMIS, the containers are called repositories, which is what you see listed in the service document.

The CMIS specification also defines a set of a few dozen content services to access this content (see figure 5).

The canDrop function in cmisconnector. js is called when a dragged object passes over a node in the CMIS repository tree.

In the case of a folder entry, the entry contains the object type property with the value of cmis: folder.

So however you set up the property definitions in your target CMIS repository, this code will try to make it work.

If you are developing CMIS tools or APIs like cmislib, it is critical that you test against as many different servers as you possibly can.

Write integrations for your favorite portal or presentation framework to enable it to easily work with CMIS repositories.

If you already know SQL, then it will be easy for you to query a CMIS repository.

You might have noticed that the CMIS HTTP parameter, versioningState=checkedout, is used in the HTTP POST operation.

The first and most obvious is to allow the source file structure to also be a CMIS system.

If you search the Internet for CMIS repositories, you can find several that you can download to try out free of charge.

So the first step was to stub out the classes and methods with Eclipse and the specification open side-by-side.

This parameter was needed to allow the file content to be uploaded to the new CMIS document.

The content of a CMIS policy is opaque to the CMIS repository, so you can use it quite flexibly.

With little more than your CMIS server's WSDL you can generate your own client-side API if you are willing to use the Web services binding.

It was important that cmislib be written as close to the specification as possible.

The CMIS standard obviously helps with those problems, but to actually get work done productively, client-side libraries are needed.

The other options, what CMIS document and folder types to use and how to handle CMIS properties, can be changed by a developer.

targetClassName Optional class type to specify the subclass of cmis: document that you will create for the new documents.

In these files, you can set the type used to create the CMIS folder or document.

Alfresco, an early adopter of CMIS, had the most mature implementation, so I started there.

All of the metadata in your original Exif tags is preserved when copying the images to your CMIS repository.

When the plug-in encounters a cmis: folder entry, it creates a node in the plug-in tree, using a folder mini-icon to represent the node.

The first point of customization is an option that lets the user specify what to use for the CMIS document name.

Sometimes a vendor's specific extension to the specification is obvious and sometimes it isn't.

In the case of documents, the value is cmis: document.

Of course, the whole point of CMIS is to access content in different repositories, not just content from one vendor.

But Python is also very prevalent on the presentation tier, so a Python-based client library for CMIS is important.

CMIS has the potential to do the same thing for content-centric applications that SQL did for relational database applications.

As mentioned in the previous section, the CMIS plug-in is built by use of XUL windows, JavaScript, CSS stylesheets, and locale files.

So when I talk about CMIS repositories, by definition, I also often talk about these systems.

If not supplied, the tool will create all documents as type cmis: document.

This parameter has the effect of checking out the newly created document in the CMIS repository.

Then the onDrop function in cmisconnector. js is used to select which value in the dropped object to use for the CMIS document name.

The cmisxcopy script attempts to map Exif property names to identical names on the CMIS side.

It lists the CMIS repositories managed by that server.

This down link is itself a CMIS feed of folders and documents.

Now that you've learned a little about CMIS, let's look at an example of how to use CMIS to access a document repository.

Nor is it true that the implementation of a CMIS repository is based on a relational database (though many are).

This content type is a way to define relationships between CMIS objects (see figure 3).

The CMIS document can also contain a content stream and renditions, such as a thumbnail view of a document.

In cmisconnector. xul, you can see the drag-and-drop options that apply to the tree control displayed in the CMIS sidebar content.

This content type is a container of CMIS documents and other CMIS folders (see figure 2).

The two most important CMIS types are the folder and document types because that is where most of the content is.

Do you mean to create an instance of cmis: document or do you want a subclass of document named CmisJpg?

If you test with only one repository, you built a client for just that one repository, not a true CMIS client.

Developers don't want or need to learn how CMIS works in order to build solutions on top of CMIS repositories.

For example, suppose you want to get a list of documents that are currently checked out. The CMIS specification tells you that

Step 2: Initialize your CMIS connection with cmislib
