Palmer & Ralls: Duty to notify
"Dealing with metadata is a reality of practicing law in today’s legal environment. Attorneys continually create and receive electronic documents. Each of these documents may contain hidden “metadata.” Metadata, when accessed, can reveal information that was never intended to be disclosed by the author of the document. For example, metadata could identify the date an electronic document was created, authored, as well as disclose previous versions and edits to the electronic document. Notably, metadata may be found in virtually any type of electronic file including pictures, video clips, documents or other types of digital files. The effective use of metadata can give one side a distinct advantage."
