Now back to the question, how do you retrieve other metadata? The question was about the Android connector but it applies to content automation. The short answer: We have special headers. Here's the definition straight from the documentation:
This header can be used whenever a document will be returned by the server. The header is forcing the server to fill the returned document up with data from schemas that match the X-NXDocumentProperties filter. So, X-NXDocumentProperties is a filter of schemas. If you don't use the header, only the minimum amount of required document properties are returned. To have more properties in the returned document, you can specify a list of document schema names:
X-NXDocumentProperties: dublincore, file
or to have all the document content, you can use the '*' character as the filter value:
If you are not familiar with Nuxeo, schemas are used to define lists of metadata.
This is intended for developers who build their own requests. If you're using a content automation client, there's a good chance this is already part of the client API. Here's an example with the Java client:
import org.nuxeo.ecm.automation.client.Constants; import org.nuxeo.ecm.automation.client.adapters.DocumentService; import org.nuxeo.ecm.automation.client.model.Documents; Documents docs = (Documents) session.newRequest(DocumentService.GetDocumentChildren) .setInput(doc) .setHeader(Constants.HEADER_NX_SCHEMAS, "*").execute();
