CrossRef Guidelines: CrossRef Glossary
The CrossRef Institutional Repositories Committee (IRC) , chaired by Bernie Rous at ACM, has developed a CrossRef Glossary - (http://www.crossref.org/08downloads/cr_glossary_1.pdf, PDF, 69k) containing common vocabulary to be used in CrossRef's policies and guidelines concerning different versions of articles and what gets assigned a DOI. Development of the Glossary was lead by Carol Richman (Sage) and Bob Hecht (Informa). CrossRef members are encouraged to review the Glossary and provide feedback to the IRC at - irc"at"crossref.org.
Important work regarding definitions for versions of journal articles is being done by a NISO/ALPSP working group . Bernie Rousis also on the NISO/ALPSP working group and the plan is to coordinate the CrossRef Glossary with the final output of the NISO/ALPSP working group.
