Store Entries
Entries store frames :-) As it's assumed, that many stored frames will use similar framemaps, framemaps are stored outside of entry. Also strings and symbols are stored outside.
Strings are contained in strings object, framemaps and symbols are stored in objects listed in symbols and framemaps catalogs.
Entry modification time is number of seconds since 1904 Jan 1st.
Field Hints tell how much space will be left for hints before start of data section. Each hint is 8 bytes long. Apparently this something have connection with strings contained in frame. When stored frame contain no strings, there is only one hint filled with zeros. After adding any string longer then 3 chars another hint is added, and both are filled. Hints are probably used for searching words in entry.
Flags usually are 0x0002. When they are 0x0003 it probably means, that entry contains VBO reference.
Data is encoded in format resembling Newton Streamed Object Format.
Storage of Strings
Strings contained within entry are stored outside of entry object. Structure of this separate object is as follows:
