I like to thank Chad for the technical implementation of the Persiistent Identifier element
(DOI) in StationXML. As no comments were received the implementation has been accepted.

Thank you,


Hello WG2,

The schema modification for the approved by WGII ( has been implemented and is ready for technical review.

Reinoud, I suggest a two week deadline for this review.

The Github pull request is here:

A direct view of the changes is here:

Modifications from the original proposal are as follows:

1) Remove prefix from Identifier value as requested by the authors of the proposal.
2) Fixed IdentifierElement => IdentifierType so consistent with example and other schema types.
3) Added an annotation to IdentifierType to describe usage:
<xs:documentation>A type to document persistent identifiers.
Identifier values should be specified without a URI scheme (prefix),
instead the identifer type is documented as an attribute.
4) Added maxOccurs="unbounded" to the usage in BaseNodeType to allow more than one Identifier:
<xs:element name="Identifier" type="fsx:IdentifierType" minOccurs="0" maxOccurs="unbounded"/>
