1. From 8 miles high to ground zero: granularity in the information landscape Gordon Dunsire

2. Preamble The information landscape Granularity of metadata Content Carrier Ground zero

3. Information landscape Topology of the common information environment See AKM9, 2005, Porec (!) Seamless, joined-up services and widest range of resources supporting the information-processing needs of all users in a community Shaped by metadata Lumps, clumps, aggregates Granularity

13. Granularity of content Global collection of all information resources International and national collections Institutional and organisational collections Special, named and functional collections Items

14. Granularity of metadata content Union catalogue (is a collection of...) Catalogue/finding aid (is a collection of...) Record (is a collection of...) Metadata statement Global finding aid (is a collection of...)

15. Metadata statements Google (web of documents) This resource (URL) contains terms bagpipes,... Only type of statement is contains terms Archives, libraries, museums (semantic web) This set of letters (ID) has author G. MacDonald This book (ID) has subject Bagpipes This object (ID) is made of goat skin 100s of types of statement

16. Granularity and lumpiness More granularity = finer detail smoother landscape easier, flexible navigation use statements to navigate Need more than one statement to identify and select a resource set of statements = record

17. Ground zero = Chain reaction Chain of metadata statements linked (open) data Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/

18. Chain reaction Controlled (not an explosion!) More like a (nuclear) power station vs ?
