This chapter explains the DAS data model, provides a brief overview of the technology used to implement DAS, and explains how the technology maps to the data model. Specifically, it:

• Explains the DAS equipment data model, including the XML data objects and options for transferring the fiber optical path and DAS instrument box.
• Explains the acquisition data model, which includes:

• Specific optical path and instrument box for a particular acquisition

• The acquisition array data and options for how it can be stored
