Hi Martin,
Some edits for your consideration:
Submission type: Presentation
Category: Developer
Abstract:
------------------------------
--------------------------------------
Apache Spatial Information System (SIS) is a Java library for developing
geospatial applications which conform to international standards. SIS
implements interfaces derived from UML published jointly by the Open
Geospatial Consortium (OGC) and the International Organization for
Standardization (ISO). This presentation will introduce the OGC vision, the
benefits of standards, the GeoAPI approach of using interfaces to support
standards, and the Apache SIS implementation of those interfaces as well as
future roadmap. This first SIS presentation will focus on metadata (ISO
19115) and georeferencing by coordinates (ISO 19111). We will give a quick
introduction to geodesy, in particular examining a common pitfall of only
specifying a latitude and a longitude that is not sufficient for uniquely
identifying a position on Earth, and demonstrate how Apache SIS can handle
this part of the complexity for developers.
Who the audience is and what we expect them to get:
--------------------------------------------------------------------
This presentation is for anyone who wishes to utilize geographic data in
their applications and would like to learn more about libraries that can
simplify their development. Attendees can expect a big picture of
standardization efforts, identify where some of the complexity stands, and
how to hide it. In particular, we will compare the complexity of using an
XML Schema Definition (XSD) available on-line to that of using UML as the
source for application programming interfaces. Finally, attendees can
expect an overview of test suites that may help them to increase their
confidence in the georeferencing performed by their applications.
How the content may help better the Apache and open source ecosystem:
--------------------------------------------------------------------
Geospatial data are ubiquitous, but the difficulty of handling them
accurately is often under-estimated. Many applications just handle
latitudes and longitudes without realizing their ambiguity. This
presentation will hopefully help to improve awareness about standards,
encourage participation in implementation-neutral efforts like those
available from OGC and GeoAPI interfaces, encourage existing application
developers to use available test suites, and encourage participation in the
improvement of those implementation-neutral test suites. Lastly, we hope to
raise interest in Apache SIS as a powerful tool for implementing standards
based geospatial development and testing.
Experience level: Intermediate

Hello all
While we are waiting for the wiki (thanks Adam for forwarding the email to
infra), below is a first draft of an abstract proposal to the Apache
conference (Denvers, April 7-9). The deadline for submission is Friday
night, this week. Do peoples feel okay with that?

Abstract:
--------------------------------------------------------------------
Apache Spatial Information System (SIS) is a Java library for developing
geospatial applications in close conformance with international standards.
SIS implements interfaces derived from the UML published jointly by the
Open Geospatial Consortium (OGC) and the International Organization for
Standardization (ISO). This presentation will introduce why standards
matter, OGC vision, the GeoAPI approach, Apache SIS implementation and its
roadmap. This first SIS presentation will focus on metadata (ISO 19115) and
referencing by coordinates (ISO 19111). We will give a quick introduction
to geodesy (did you knew that specifying latitude and longitude is not
sufficient for uniquely identifying a position on Earth?) and see how
existing resources can handle part of the complexity for the developers.
Who the audience is and what we expect them to get:
--------------------------------------------------------------------
The audience is anyone who wish to handle geographic data in their product
and would like to familiarize with such topic. Attendees can expect a big
picture of standardization efforts, identify where some of the complexity
stands and how to hide it. In particular we will compare the impact on
complexity between using the XSD available on-line or the UML as the source
for application programming interfaces. Finally, attendees can expect an
overview of test suites that may help them to increase their confidence in
the georeferencing performed by their product.

Geospatial data are ubiquitous, but the difficulty of handling them
accurately is very often under-estimated. Many applications just handle
latitudes and longitudes without realizing their ambiguity. This
presentation will hopefully help to improve awareness about standards,
encourage participation to implementation-neutral efforts like OGC works
and GeoAPI interfaces, encourage existing products to test themselves
against available test suites, and encourage participation to the
improvement of those implementation-neutral test suites. Then we hope to
raise interest in Apache SIS as one powerful implementation of the above.
