Hi,

When using the client, the client does some work for you (such as prompting the server to extract metadata from files you upload).
When using CIFS, you are going straight to the server, so the extra work the client does on your behalf is omitted.

To automatically get metadata extracted CIFS files, you can create a rule on the space you are uploading to that does the action "Extract common metadata fields from content".
This will then do the same thing.

Hope this helps,

Steve

Hello!

It works, many thanks!
Alfresco correctly extracts the Author.
I have noticed the created and modified dates are the dates when the document was introduiced into Alfresco and not the dates when the document was really created/modified… Why? How to also pick up the good dates?

Just a question. Is it possible to use to configure a file instead of creating a rule to automise the metadata extraction?

Thanks.

Hi Steve,

"Extract common metadata fields from content" works, but it extracts only the Author property, why doesnt it extract title and description?
Anyway i can achieve to extract both title and description?

Also i have the same question wrt modified/created date.

Thanks,
Lakshmi

Hello,

When we use CIFS, Author, title are correctly extracted but not the dates… dates which are written are those when the document was introduiced into Alfresco and not the real date of creation/modification…

Are we only 2 having this problem?

Hello,

Created and Modified dates are relevant to Alfresco repository.
The "real date of creation/modification" is file system information, not content metadata. Metadata Extraction looks into binary content to find properties values; as "real date of creation/modification" are not stored in binary content, they can't be extracted.
Am I clear enough ?

Regarding title and author, are you sure your document has such information ?

Charles

Hello,

Thank you for your answer cleseach!
I understand that the date information are not writen in the file itself as Author or Title do, but in the file system.
So there is no way to collect it with Alfresco, am I right? If not, how to get it, is there another way to do it?

I'm not a CIFS expert, but I think your right.
