# 14 The Ipe file format

Ipe can store documents in several possible formats. Among them are standard PDF and Postscript, which can be read by any application capable of opening such files, such as Acrobat Reader, Xpdf, or Ghostview. (Ipe embeds its own information inside PDF and Postscript files. The way this is done is not documented here, and may change between releases of Ipe.)

There is one other Ipe file format, which is a pure XML implementation. Files stored in this format can be parsed with any XML-aware application, and you can create XML files for Ipe from your own applications. The tags understood by Ipe are described informally in this section. A formal DTD will be provided in due course (volunteers?).

Tags in the XML file can carry attributes other than the ones documented here. Ipe ignores all attributes it does't understand, and they will be lost if the document is saved again from Ipe. Ipe will complain about any XML elements not described here, with the exception that you can use elements whose name starts with "x-" freely to add your own information inside an Ipe file.
