Presentation Plan:Overview of openModellerOMWS: an open standard for distributed ecological niche modellingopenModeller in relation to TDWG

openModeller Overview

Project started by CRIA, Brazil in 2003An Open Source project hosted on sourceforgeWritten in C++ with SWIG language bindingsProvides an environment for carrying out fundamental ecological niche modelling

openModeller Architecture

libopenmodeller is the core componentProvides data IO for gdal supported raster formatsSeamlessly manages rasters in different formatsHandles sampling of rasters at occurrence sitesWrites model outputs to raster files

Algorithm pluginsAlgorithm plugins extend the library with support for various ecological niche modelling implementationsGARP, Bioclim, CSM etc are already implemented

openModeller ArchitectureopenModeller Desktop

A graphical user interface for openModellerVersion 0 : A wizard based gui (stable version)Version 1: A traditional desktop application (unstable)

openModeller console interface also available

openModeller WSI

Using SOAP (Document / Literal)Separate XML Schema for types & elementsAPI is very simple (few methods)Prototype implementation: gSOAP on server side, Perl with SOAP:Lite on client side (console) and gSOAP on client side (GUI).Protocol not specific to openModeller

10

getLayers()Used to determine what environmental layers are on the server.

11

getLayers()Presented to user as heirachical treeLayers have identifiers that could resolve files, database urls (WCS in the future)

12

getAlgorithms()Used to determine what modelling algorithms are on the server.

13

getAlgorithms()Presented to user as listUsers can set parameter valuesDocument includes descriptive data to aid user decision making

14

createModel()Uses locality, algorithm and layer data to invoke a model creation job on the server -> Job Ticket

15

createModel()Returns a serialised model definition document

16

projectModel()Used to render a probaility of occurence map

17

getMapAsUrl()

Additional Methodsping()getProgress()getLog()getMapAsUrl()getMapAsAttachment()

19

Integration With TDWG/OGCAutomated resolution of taxonomy (GBIF Portal)Automated retrieval of occurrence data (WFS + GML)Metadata - Provenance of models (what species was used for this model, using which data from which institutions etc) (OGC)Access to environment data via WCSAPIs for analysis (missing from TDWG)
