A Document Succession Identifier (DSI) is a new kind of PID that has properties of hash-based PIDs like SoftWare Hash Identifiers (SWHIDs), but a DSI can be used to identify research documents that are correctable.
Version 2.0 of Hidos, a command-line tool for working with DSI, is now available and you can go through a tutorial demonstrating its use at:
Hashes, like MD5, are usually only used to identify a frozen copy of a file. A DSI differs in that it identifies a succession of document editions. The editions are frozen, but the succession can be amended. Like hashes, a DSI is defined by algorithms rather than a central database or authority (as is the case for a DOI).
This underlying technology in Hidos and the DSI is motivated for use with a specific type of document: a Baseprint document. More information about Baseprint documents is available at https://perm.pub. But Hidos and DSI is designed to be relatively independent of the document format.
