<ali:free_to_read> Free to Read (NISO ALI)

A flag indicating that the document content can be read or viewed at its current location by any user without payment or authentication; it is free to be read.


This element is defined in NISO Access License and Indicators (ALI) NISO RP-22-2015.
This is a simple indication of the status of the standard that does not make any statements about additional reuse rights or restrictions. Absence of this element in a document does not indicate its negation; it merely indicates that a user would need to look to other information to ascertain the status of the document.
Date Attributes
Start and end dates can be placed on the free-to-read status using the attributes @start_date and @end_date. Start and end dates can be used to record delayed access, special offers, etc., where the content is free to be read for a period of time or after a particular date. The absence of both start and end dates indicates a permanent “free-to-read” status.
Related Elements
Use of this element is independent of both the NISO ALI <ali:license_ref> and the <license> elements.
Permissions and Licensing Elements: NISO STS has several elements that deal with the usage, permissions, and licensing. Two of these elements(<ali:free_to_read> and <ali:license_ref>) are provided for users of the NISO Access License and Indicators (ALI) NISO RP-22-2015 specification. The other element (<license>) is for more general or supplementary license information.
  • <ali:free_to_read> — This NISO ALI element is a simple flag whose presence indicates that the document is free to be read, without making statements about any additional reuse rights or restrictions. Date attributes can specify when the document is free to be read.
  • <ali:license_ref> — This NISO ALI element points to a public license or waiver. By “public”, NISO ALI means that the offer is generally and not privately offered. Such a license may be either human or machine-readable text that explains the terms of use or reuse for the content.
  • <license> — An element from JATS whose content describes a set of conditions under which the content may be used, accessed, and distributed. This element was provided to hold the license text. The 2015 NISO ALI recommendation is to store in the XML document a URI that points to the license instead of the full license text. For organizations who adopt the NISO ALI recommendation, the <license> element can be used to hold a short representation of the license, such as a sentence or two, which is used for display. Alternatively, an organization can choose not to implement NISO ALI and to put the text of the license in <license>.
    The <license> element takes the @xlink:href attribute to point to the text of the license. However, the new NISO ALI element <ali:license_ref> performs the same pointing function. NISO STS follows JATS best practice in omitting the @xlink:href attribute from <license> if a NISO ALI <ali:license_ref> is used.
