Associating content with a new Object

We store scanned images (TIFF files) as content in Documentum 6.5 SP3. We also create custom Objects representing these images and as well as holding various attributes of images (e.g. number of pages and other fields via OCR). Currently in production we got some images released (via Kofax) to the wrong type of object - normally these images are associated with a biz_image object but somehow these were released with the biz_addressSlip object selected in Kofax. Now we want to write Java code to basically create biz_image objects for these images and delete the incorrect biz_addressSlip objects. I am new to Documentum's DFC API and have following questions:

1. I have created a program in Java that successfully query for these biz_addressSlip objects and then create the biz_image object copying its properties. What I am missing is somehow associate this newly created object to point to the image contents currently associated with biz_addressSlip object. I found the bindFIle() method on IDfSysObject that seems like what i needed to do this

2. Next step is to delete the biz_addressSlip object BUT how documentum will handle the associated image? Will it delete it too? Do we need to somehow "un-associate" the image with this object first? How? Any unbindFile() method?

If anyone could point me to the APIs i need to look at for handling this "association" between content and objects, that will be really great.

TIA!

Thanks for this suggestion. I actually tried in DEV using the bindFile() method and it seems to be working fine - i can get to my content using the newly created object after bindFile() has been called upon it. I can also delete the original object and the image content stick around - not getting deleted. Its a much simpler solution so i am hoping there is no downside to it.

Make sure you have a backup before you start.

You are going to build the relationship by updating attributes yourself. The information is in the

Object Reference Manual, dm_sysobject, content section and dmr_content object section

the relationships are (and you have to update both otherwise dm_clean or filescan will erase them on you once you break the relationship with the wrong type):

content file <- dmr_content <- dm_sysobject (meta data)

The content has:

r_object_id

parent_id R Object Ids of SysObjects that contain content (update this one)

page R

rendition

content_size

set_time

set_client

set_file

Sysobject has:

r_object_id

i_contents_id S

a_content_type S

r_content_size S

r_page_cnt S

you will end up with

content file <- dmr_content <- dm_sysobject (meta data)

^- dm_sysobject (meta data)

once you happy everyting is the way you want you clean up, which will also just be some updates and then once the relationship is broken you can delete the object you don't want any longer

Try it in dev first

Hope this helps

Hi MEJazz, can you mark "eikrid" post as the "correct answer" so other online members can see your initial post with the answer within in, also he can get credit for his contribution Let me know if you have questions.

MEJazz

Manni, actually i did not tried eikrid's proposed solution; it was involves manipulating internal meta-data. I actually came across this simple API call bindFile() that did what i wanted to do. Thus i marked the question as answer assumed.

If someone sees a problem with using bindFile(), please let me know. Otherwise i am all for simple solution.

Just to be certain, make sure you run dm_clean / dm_filescan job after once you deleted your addressSlip objects and make sure you still have the contents for your newly created objects that you used bindFile().

Hi,

bindFile() is exactly what you were looking for, so you shouldn't experience any problem

I have similar requirement, in which I do not want to bind the content with new object type.

I want to copy the content from type "A" object to type "B" object and "A" and "B" ar independent, for example, Once copy is done, will be using Type "B" object for retention perios and workflow processing.

Can some once suggest , is there any better option, getting /copying the content ?

Or i create new Thread / Question ?
