Dear all,
During the Edinburgh meeting we had problems defining the way we were
going to communicate to develop a core of clases-ontology-list-
whatever for TDWG.
While reading the OpenGIS Sensor Observation Service (SOS)
Implementation Specification I have found that they seem to have the
same problem of people very used to XML Spy and its XML Schema
representation for modeling. They enforce the use of UML diagrams but
use XML Spy diagrams for clarification.
"5.2 UML Notation
Most diagrams that appear in this specification are presented using
the Unified Modeling
Language (UML) static structure diagram, as described in Subclause
5.2 of [OGC 05-
008].
5.3 XML schema notation
Most diagrams that appear in this specification are presented using
an XML schema
notation defined by the XMLSpy1 product and described in this
subclause. XML schema
diagrams are for informative use only though they shall reflect the
accompanied UML
and schema perfectly.
"
And then continue explaining the different things that appear on an
XML Spy diagram (elements, optionality, recursion, sequence, choices,
etc.)
I am sending this to the TAPIR mailing list because I think this
could be really useful for the specification document. We can just
point to them and we don't need to describe all this :)
The document I am talking about can be found at:
http://www.opengeospatial.org/specs/?page=requests&request=rfpc32
And is in its RPC process right now.
Javier.
