Type: External identifier
From Buddha-Nature
"External identifier" is a variant of the Text datatype to describe external resources (URI based) and requires assigned properties to declare an External formatter URI.
The purpose of the buddha-nature website is to provide a resource hub for trustworthy information for learning about and teaching the concept of buddha-nature, its associated texts, teachings, lineages, and relevant Buddhist ideas. Unique content will be shared here, but the site will primarily act as a broker for other projects and authors that have already created quality materials, which we will curate for a wide range of audiences.
