An EPC file is a container file following the Energistics Packaging Conventions (EPC). For DAS, it stores all the data objects described in Section 19.1 Data Model and Technology Overview, which includes the metadata for the raw and/or processed datasets (if any). Each EPC file must refer to only one DAS Acquisition. However, one DAS Acquisition may have multiple EPC files referring to it, depending on the business use case.
- For more information on how HDF5 files are formatted, see Section 19.5 Defining the DAS Acquisition Data (Raw and Processed Data).
- For more information on how the HDF5 files are referenced from an EPC file, see Energistics Packaging Conventions Specification.
EPC is a set of conventions that allows multiple files to be grouped together as a single package (or file), which makes it easier to exchange the many files that may make up a model.
It is an implementation of the Open Packaging Conventions (OPC), a commonly used container file technology standard supported by two international standards organizations. Essentially, an EPC file is a .zip file. You may open it and look at its content using any .zip tool. EPC is also part of the CTA, and how it works is described in the EPC Specification.
