I've made a few enhancements to the OpenCirce Organisation Hub
http://opencirce.org/org/- the two groups of DAC codes have been divided into Channel and Agency codes
- organizations mentioned in the IATI data ( as currently loaded into the AIDVIEW database) are listed in the appropriate 'realm' and are searchable
- many (but not all yet) listed organizations have been explicitly extended with website links
- where listed ids donot link to valid organisations, aliase links are being added as time permits
- changes to derived links to keep up with changes in interfaces to external sources
Please let me know if you find this service useful (or not!) and how you would want it improved.
