URIs for schema elements

[smrgeoinfo]

in LINKML yaml, make base URI
https://w3id.org/isample/schema/1.0/

schema entities and properties will have uri like https://w3id.org/isample/schema/1.0/{element}

set up w3id config to dereference to
https://isamplesorg.github.io/metadata/{element}.html

for now all uris dereference only to html.
