removing default aspects like exif and versionable

ad-int-en — Thu, 14 Apr 2011 09:24:43 GMT

is it possible (and where) to remove the default aspects for images (or other document types)?Specifically I want to remove the exif aspect from all newly uploaded images files and the versionable aspect from all files in general.Thx for your input in advance!

AD-Int-en,

I believe you need to use specialized software such as this metadata remover – before uploading something into Alfresco – to get rid of Exif and other photographic information. And to remove versionable aspect, reuploading of all images is the only way.

thx a lot for your reply, but I want to remove the aspect from the alfresco document node, not the exif data itself from the document.
The EXIF aspect was just one specific example, but I would like to configured which aspects are added to specific document types by default.

best regards
Paul

There's two things going on here.

a) when you import your images there's an extract metadata action running that is extracting the Exif stuff. You don't say what the problem is but there's several ways to change the behaviour, the first choice is probably to configure the mappings of the metadata extractor to not map the exif properties. (Or to select a subset of properties you do want to map since you will still probably want the title and name etc). Take a look at TikaAutoMetadataExtracter.properties

b) The versionable aspect is a separate issue unrelated to metadata extraction. But in general you can remove it from the folder that you are uploading your content to and that will stop new files inheriting the versionable aspect. One important exception to this is if you are uploading to the Share interface which has some hard coding for versioning.
