The library community has well developed bibliographic description traditions that with some adjustment for digital resources, such as the MODS development exemplifies, will serve the digital future. In the larger metadata picture, the development of METS is a big step toward bringing to non-descriptive metadata the stability needed for a smoothly functioning Internet environment where electronic resources flow seamlessly between systems. These developments relate well to the OAIS (Open Archival Information System) Reference Model (www.ccsds.org/RP9905/RP9905.html), which helps to define the processes and boundaries in creating, managing, sustaining and serving digital resources. The METS package can be used to collect digital resource metadata for submission to the repository, serve as the place for the metadata within the repository and be the supplier of information to the tools that provide the resources to the patrons.
