Open Educational Resources (OER): Open Educational Resources are teaching, learning and research materials in any medium-digital or otherwise that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation, and redistribution by others with no or limited restrictions. https://hewlett.org/strategy/open-educational-resources/
Open Access (OA): Making research outputs permanently and freely available via the internet, permitting a user to read, download, copy, distribute, print, search, or link to the full text of these articles, crawl them for indexing, pass them as data to software, or use them for any lawful purpose, without financial, legal or technical barriers other than those inseparable from gaining access to the internet itself. This definition is based on the Budapest Open Access Initiative (2002).
Gold Open Access: A work is open access immediately via a fully open access publication outlet. This is considered 'born' open access.
Green Open Access: Making research outputs open access via an institutional repository.
Hybrid Open Access: Making an individual work open access in an otherwise subscription-based publication outlet.
Metadata: Structured information about the attributes of a research output or collection of research outputs that enables that output or collection to be identified, retrieved and managed over time. Typically includes fields such as title, authors, journal name, volume, issue and page numbers, and may also include data by or about any grants associated with the output. https://www.gs.unsw.edu.au/policy/documents/openaccesspolicy.pdf

Creative Commons: Creative Commons is an internationally active non-profit organization that provides free licenses for creators to use when making their work available to the public.

Publication Fee: Sometimes called a processing fee or author's fee. A fee charged by some OA journals when accepting articles for publication in order to cover the cost of production. It's one way to cover production costs without charging readers and erecting access barriers. While the bill goes to the author, the bill is usually by the author's funders or employer, not by the author's out of pocket. http://libguides.nyit.edu/c.php?g=848478&p=6105977
