Unable to update metadata using metadata group

This morning I have been having trouble updating metadata via the following code;

'copy metaData from placeHolder asset
Dim metaData As MBPSCRIPTMODEL2Lib.MBObjectCollection = placeHolderAsset.GroupMetaData(copyMetaDataGroup.Identifier)

'update asset with metaData copied above
asset.ReviseMetaData(metaData)

I am getting the following error exception "The user is not authorized for the action or access to the object" on ReviseMetaData.

This was working until this morning.

I am am however able to add individual metaData to assets.

What UID are you using to authenticate? Pro'ly permissions got changed in the folder that this asset resides in. Are you checking for permissions in your code before you do a revise/update metadata?

I have resolved this issue now.

Can you please post back how you resolved it?

the mistake I was making was adding the metaData "Name" to the copyMetaDataGroup group. Apparently one cannot update the Name metadata.

Let me add a quick explanation of why name isn't actually metadata. When you create a reference to an asset in MediaBin they share the underlying file including all revisions and all metadata (i.e., a change in one affects all the other references just like a unix "hard link" ). References in MediaBin are displayed in a similar manner to Windows shortcuts, but unlike Windows shortcuts (and unix symbolic links) a reference can never be dangling (i.e., deleting the underlying asset removes all references).

Okay, references share all metadata bt they can have different names! Hence names cannot really be metadata.
