This is my understanding of the problem. I could, and most likely am, wrong.

In external application, create annotation. Annotation is created and
assigned an Object Identifier. The file is saved. At a later date the PDF
file is accessed using a script or the same application that searches for
the Object Identifier and pulls its content into a file or opens the pdf at
the page of the annotation. The logical method would be to pass the Object
Identifier via command line.

The proper method, according to the PDF 1.7 spec, page 63, is to assign
unique Object Identification numbers to all indirect objects and then to
increment content while maintaining the original Object Identifier. The
examples are in Appendix G, pg. 1075. Pretty much all viewers that allow
annotations use a short-cut, and increment the Object Identifier with each
write as annotations change or other segments are added to the file. So for
example, I could open a pdf in Adobe Acrobat Viewer, make an annotation,
take note of the Object Identifier and then save the file. I could then
open the file in any other viewer, change the annotation by adding or
removing content and then save the file. This would break the Object
Identifier by changing it, making any attempt to go to it in the future
using the original Object Identifier futile.

If the Object Identifier were to remain constant, then pulling it up at a
future date with a different application or script would be possible. As it
stands, it isn't.
