<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.
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.
