Issues and Challenges • Adding historical data • Performance • Licensing • Improving the Geoparser • General Issues • 2

When’s a Feature? Plus the temporal dimension! • 3

Feature Typing • Is the ADL Feature Type Thesaurus flexible enough? • Does it make sense for HE/FE? • Are there alternatives? • Issues relating particularly to admin boundaries • Lack of comprehensive compendium of modern and historical geographies • 4

Performance - the art of the possible • Need to investigate different architectures • Always want responses faster but how fast should we expect a response? • What are the acceptable parameters for response times? • Are clients/users prepared to wait longer for answers to more complex queries? • 5

Data Licensing • HE/FE only? • Additional data and licensing – What additional data should be in the gazetteer? – What restrictions are there on usage? – If specific data are felt to be needed, who should pay? • 6

Geoparser • Do we want / need a Geoparser? • Technical aspects: – Improving textual analysis & placename disambiguation – Improving tools to assist in document indexing and metadata creation – Improving general performance • 7

General Issues • How do we convey the complexity of what is being attempted to the novice? • How do we improve interfaces for reference use? • How do we optimise machine 2 machine negotiations sensibly (don’t want queries of the form, ’Give me all the features for England’!!!!) ? • What protocols should we adopt? • 8

Specific Issues • How to deal with variant names? • Data validation/quality assurance issues? • Confidence in answers provided • Provenance / authority of data used to populate geo. Xwalk • Primary name • Multiple feature typing • Others? ? • 9
