Custom form for adding or editing a webpage associated with an individual. The primary page,
|
||||
ManageWebpagesForIndividual, should forward to this page if: (a) we are adding a new page, or
|
||||
(b) an edit link in the Manage Webpages view has been clicked. But right now (a) is not implemented.

|
||||
Object properties:

core:webpage (range: core:URLLink)

core:webpageOf (domain: core:URLLink) (inverse of core:webpage)
|

Class:
|

core:URLLink - the link to be added to the individual
|

Data properties of core:URLLink:

core:linkURI
