Comparing and merging complex data structures

A method for merging electronic files signifying non-textual content, the method comprising:

• obtaining a first electronic file in a first format and a second electronic file in a second format signifying non textual content;
• converting the first electronic file and the second electronic file to a systematic format;
• and
• merging the first electronic file and the second electronic file to generate a merged electronic file in the systematic format,
• wherein the systematic format is configured to enable comparing between different electronic files by representing elementary non-textual objects in a surjective representation thereby facilitating consistent comparison between elements in the files in different versions and/or files, and
• wherein the surjective representation is surjective onto a plurality of possible ambiguous representations in the first format.

A revision control method for electronic files representing non-textual content, the method comprising:

• obtaining a first electronic file, comprising data signifying non-textual content in a first format;
• deconstructing the non-textual content data to elementary non-textual objects having a representation in the first format;
• methodically converting the representation of the elementary non-textual objects from the first format to a systematic format;
• aggregate the representation of the elementary non-textual objects in the systematic format, to generate a second electronic file comprising data signifying the non-textual content in the systematic format,
• wherein methodically converting the representation of the elementary non-textual objects from the first format to the systematic format comprises utilizing a surj ective representation of the elementary non-textual object.

A revision control system for electronic files representing non-textual content, the system comprising

• a non-transitory memory, configured for storing thereon a repository revision of an electronic file;
• and
• a processing circuitry configured to:
• obtain a first electronic file, comprising data signifying non-textual content in a first format;
• deconstruct the non-textual content data to elementary non-textual objects having a representation in the first format;
• methodically convert the representation of the elementary non-textual objects from the first format to a systematic format;
• and
• aggregate the representation of the elementary non-textual objects in the systematic format, to generate a second electronic file comprising data signifying the non-textual content in the systematic format,
• wherein methodically converting the representation of the elementary non-textual objects from the first format to the systematic format comprises utilizing a surj ective representation of the elementary non-textual object.
