Container element for copyright and license information for the entire article or for the object which contains the <permissions> element.
The <permissions> element is used in two contexts: inside the metadata of an article and inside the specific metadata for a block object such as a section, figure, or table.
When used in the article metadata, <permissions> refers to the entire document, containing the document’s copyright, copyright statement, permission to read, license, etc.
When <permissions> is contained in an object such as a figure, for example, it records the ownership of the intellectual property of the object, such as the current copyright statement, copyright year, etc. for that figure. If the figure was previously published or has a different author from the article, that information should be described using the <attrib> element, which is a container element for information concerning the origin of the figure, extract, display quote, poetry, or similar element to which it is attached (where it came from, who said it, who created it, etc.).
Contents of Permissions
The sub-elements of <permissions> are repeatable. If multiple values are applicable (such as multiple copyright years), they should be tagged separately rather than as multiple values within a single element. Repeated values do not describe the source of the material, they describe the current Intellectual Property for the article or object.
