Financial Metadata

"Metadata" is information about information.  A familiar example of metadata is that which describes books: it can include the author, title, publisher, edition, date and place of publication, illustrator, type of illustrations, number of pages, and much more.  Metadata about an electronic file could include author, file type, date file was created, update dates, file size, type of contents, etc.  Metadata helps academic researchers understand the item they are encountering.  A great deal of BIM data (Building Information Modeling) requires metadata.  The proposed X9 standard is information about financial information.
