totally different

WHAT DO WE HAVE?● Consultants● Curators● Knowledge

WHAT DO WE WANT?● Data Available

● To the right people

● Updated regularly● Maps

● Related Species

● Be able to identify species

● Minimise duplication of effort

HOW DO WE GET IT?● Data exchange format

● DarwinCore– DublinCore for biology

● Global Initialitves

● Data Mungeing● Pentaho Data

Integration● http://kettle.pentaho.com

Munge Munge Munge● Google Refine?● Pentaho

● Connect to SQL Server

● Transformations● Validations

HOW DO WE GET IT?● Drupal Modules

● Core

– Fields

● Contrib

– Drush, drush, drush

– Features

– Migrate

– Geofield

– Openlayers

– Views

– Rules

– Flag

– Display Suite

ID Tool● Species Profiles in

a node type● Attribute field

● (hook_field_info)– Field Name– Field Value

Adding Value● Collection is

dynamic● Identifications

change● Names change

● Curators check identifications

● Correct where necessary

Adding Value● Node type for

specimens● Taxonomy for

names

● Geofield to store spatial data● http://drupal.org/

project/geofield

Migrations● Base class to define

a migration● Run Pentaho

– exec();

– escapeshellcmd();

● Import Names● Import Specimens

Migrations● Dynamic Migration

● Extend DynamicMigration● MigrationBase::registerMigration();

Migrations● Gotchas

_migration.inc● Don't believe

everything you find in a database– Eg Date Changed

● Behaviors– Popup– Geolocation– Draw

● Gotchas● Define a map per

in that map

● Try MapBox & TileMill● developmentseed

● Views Hacks● Flag● Custom module
