DotCMIS API to associate a custom type to a document

Hi,We are using the DotCMIS APIs to upload documents to a repository in alfresco. We are able to upload and add the default propertes to the document. We also have some custom types that have already been added into the alfresco environment. When we use the share url and then upload a document manua

Look at the "Creating a Document" example on <a href="http://chemistry.apache.org/dotnet/getting-started-with-dotcmis.html">this page</a>.

Now, instead of specifying "cmis:document" as the content type, specify the ID of your custom content type. For example, if you defined a custom type called "sc:whitepaper" then you would specify "D:sc:whitepaper" as the type in your CreateDocument call.

To set custom properties, just use the ID of the property. So you might set "sc:clientName" with a value, for example.

Hope that helps,

Jeff

Hi Jeff,

It works. Thanks a lot for it.

We have another question. Currently in our sample app, we tried uploading files up to 300MB and it worked. But in the real life scenario we would have documents up to 2 - 3 GB in size. Will the CMIS APIs support such large file upload. If not then is there an alternative way to do it.

Regards,
Rita

CMIS 1.1 supports the ability to append a content stream. So you could essentially buffer your write by breaking your upload into chunks and then calling append content stream with each chunk, see http://chemistry.apache.org/java/0.11.0/maven/apidocs/org/apache/chemistry/opencmis/server/impl/browser/ObjectService.AppendContentStream.html

Because this is CMIS 1.1 you must use Alfresco 4.2 or higher for this to work.

Hi Jeff,

I am using DotCMIS that i downloaded 2 weeks back and the alfresco version that we are using is 4.2.2 However I don't get the option document.appendContentStream

Any idea what i am missing? Does DotCMIS support this feature? We are trying to consume Alfresco in our dotnet application and hence using DotCMIS.

Regards,
Rita

I may be that the DotCMIS library hasn't been updated for CMIS 1.1 yet. If you are using 4.2.2 the server supports it. The worst case is that you could use the lower-level binding to invoke it directly. If you want to learn more about it by reading the spec, start <a href="http://docs.oasis-open.org/cmis/CMIS/v1.1/os/CMIS-v1.1-os.html#x1-150008">here</a>.
