Adding custom properties to CMIS Server.
Hi,
I have been trying to add functionality to my custom CMIS server that
allows for custom properties to be set. The CMIS server implementation
is an adaptation of the OpenCMIS server framework stub, where the File
System structure has been replaced by object based storage with
ElasticSearch. I need these custom properties to allow not only
"cmis:file" types, but also "cmis:folder" types to have a url property
where you can download the appropriate metadata file. The "cmis:file"
type has a contentStream where you can find the actual content (usually
a PDF), where this custom property is also required to link to the
metadata file of the "cmis:file".
Based on the instructions at this URL:
(https://chemistry.apache.org/docs/cmis-samples/samples/properties/index.html),
I have tried multiple variations of the following code:
// CMIS 1.1 properties
if (context.getCmisVersion() != CmisVersion.CMIS_1_0) {
addPropertyString(result, typeId, filter,
PropertyIds.DESCRIPTION, null);
List<String> secondaryTypes = new ArrayList<String>();
secondaryTypes.add("tmlo:metaDataFile");
addPropertyIdList(result, typeId, filter,
PropertyIds.SECONDARY_OBJECT_TYPE_IDS, secondaryTypes);
addPropertyString(result, typeId, filter,
"tmlo:metaDataFile", tmloCmisObject.getMetaDataFileLocation());
}
/Note that the syntax is slightly different from the URL, because the
framework implementation comes with the "addProperty[X]" functions as
opposed to the "properties.put" found in the URL.
/
This results in the following exception, however, when trying to connect
to the CMIS server:
CMIS Exception: objectNotFound Type 'tmlo:metaDataFile' is unknown!
Error Content: <html><head><title>Apache Chemistry OpenCMIS -
objectNotFound error</title><style><!--H1

Status 404 -

I have not been able to find out what causes the error. There have been
responses to similar questions that "custom properties should be defined
in the repository", but they come without information on how to actually
do that.
If further information is required I will gladly supply it.
Best regards,
Tycho Nijon

Re: Adding custom properties to CMIS Server.

Hi Tycho,
I assume you used the OpenCMIS FileShare code as a starting point. If
so, there should be a class FileShareTypeManager. (You may have renamed
it.)
The type definitions are set up in the constructor.
To make your use case work, you need two additional type definitions:
The base secondary type and your secondary type.
The class TypeDefinitionFactory should help you constructing these type
definitions.
