If you own the content and the annotations it would be neat to build a
system, maybe using operational transforms, that updates the annotations.

For Hypothesis, we use a different approach and have built a system to
extract text from the document and search it, with some change tolerance,
to anchor the annotation based on the quote when the document structure has
changed.

Over the next month the whole team will be working together, leading up to
the I Annotate conference, to prepare these changes for easy integration
upstream.

You can check the activity at our fork, hypothesis/annotator, for a sneak
peak. Also watch the "changing content problem" issue on annotator for news
about this.
