Preserves is a data model, with associated serialization formats.
It supports records with user-defined labels, embedded references, and the usual suite of atomic and compound data types, including binary data as a distinct type from text strings. Its annotations allow separation of data from metadata such as comments, trace information, and provenance information.
Preserves departs from many other data languages in defining how to compare two values. Comparison is based on the data model, not on syntax or on data structures of any particular implementation language.
