Discussion

The Open Packaging Convention (OPC) is the packaging portion of the Office Open XML (OOXML) ISO/IEC 29500 specification that originated with Microsoft and the Office suite before being submitted through ECMA and ISO. It is a ZIP-based package that differs from the others most noticeably in its ability to specify relationships between items in the package. This provides more flexibility through extra levels of indirection, but also added complexity. It also describes specific details of the ZIP structure in much greater detail than the other specs.
