WWID

A WWID (World Wide Identifier) number is used to keep track of storage devices. If you come across one in metadata you may be able to use it to hunt down the type of device being referenced. It may also be referred to as the WWN, the World Wide Name. An organization unique identifier (OUI) may comprise part of the WWID. A list of OUIs is located here:

So this example for a Cisco device:

. . . can be cross-referenced with this information:

regex search for one or more instances of a character set

When you add a plus sign '+' after characters identified within square brackets in a regular expression search, the search will find any instances where one or more of these characters appear. So this search:

[A-D]+[0-5]+[a-c]+

. . . will find strings which begin with one or more instances of the uppercase letters between A to D, one or more digits between 1 and 5, and end with one or more of the lowercase letters between a and c.

Clean metadata from multiple PDF files

Note that you can remove configurable metadata (metadata that can be added or modified by an application user) using Adobe Acrobat.

When viewing an individual PDF, go to File . . . .Save As Other . . .Optimized PDF

Then in the PDF Optimizer dialog box, check off just the box for 'Discard User Data', and select the individual options for different categories of metadata to the right.

Even better, set up an Adobe Acrobat action to scrub the metadata from multiple PDF files. Under Tools . . . Action Wizard . . . Create New Action, select the option in the Protection section for 'Remove Hidden Information'. Bring it over to the right, and then after being sure to uncheck 'Prompt User' so the action doesn't make you save each PDF, click on Specify Settings. You will probably want to uncheck the options for 'Bookmarks' and 'Links' since the final version of a PDF of a court filing may need to retain these features.

The action will give you the option to add one file or an entire folder of files. Start the action to process the files.
