how to fill format (a_content_type) while creating a document in DFS?

问题

I am developing a DFS application (оn С#) that imports a document into Documentum as dm_document. A document may be in any format – DOC, DOC, PDF, whatever. Thus, when I create a document, I have to specify corresponding format (it will be put into a_content_type): “gif”, “msw8” etc.

How can I solve this task? I have looked through DFS_66_reference.pdf and DFS-SDK Help – do not see simple solution yet. Can you give me an advice?

回答1:

I usually do what David suggests for common formats that I am expecting to encounter. This has the added benefit of giving you a reference to look at while debugging your application. For other formats, you can make the following query.

DQL:

SELECT name from dm_format WHERE dos_extension = lower('<extension>')

Note that this is not always reliable, because it could return multiple results for an extension (XLS is a good example), so you should decide how to handle multiple results. You may have to ask the user in that case.

I would recommend caching the responses in your application so you are not making this query needlessly. As David said above, these values do not change unless you change them.

Are you asking how to match the dos extension to Documentum format ?

If yes, the simplest is to simply hardcode the mapping directly in your application.

In Webtop file wdk/app.xml there is the mapping it uses.

Here is what I have in mine :

              <format extension="txt" name="crtext"/>
              <format extension="xls" name="excel8book"/>
              <format extension="doc" name="msw8"/>
              <format extension="ppt" name="ppt8"/>
              <format extension="vsd" name="vsd"/>
              <format extension="zip" name="zip"/>
              <format extension="wpd" name="wp8"/>
              <format extension="psd" name="photoshop6"/>
              <format extension="au" name="audio"/>
              <format extension="jpeg" name="jpeg"/>
              <format extension="jpg" name="jpeg"/>
              <format extension="html" name="html"/>
              <format extension="htm" name="html"/>
              <format extension="ai" name="illustrator10"/>
