Expose Schema’s terminology in user interface

13. EAC’s Implicit Information Architecture
Expose Schema’s terminology in user interface
Pick metadata that could get turned to facets

14. EAC’s Implicit Information Architecture
Expose Schema’s terminology in user interface
Pick metadata that could get turned to facets
XTF Section Types / based on hierarchy of EAC

15. Front End Stack
golden grid http://code.google.com/p/the-golden-grid/
form style http://formalize.me/
jquery and jquery ui
hoverIntent for advanced search
google analytics with event tracking
Uservoice forum, google spreadsheets for feedback

16. XTF XSLT Framework
Access system is based on a customized branch of CDL Publishing Group’s XTF
pre filter - do special tokenization to create custom EAC facets
https://docs.google.com/document/d/1wP9x6sdOZTagJNQXoyJfPh0Y6UzQgqLwLI86WSlIPbk/edit?hl=en_US
query parser - CGI params to XTF query XML
result formatter - XTF results to HTML
doc formatter - EAC-CPF to HTML

17. Tinkerpop Graph Stack
http://www.tinkerpop.com/
Property Graph Model
graphML
RDF Sail support

18. social graph visualization
EAC to graphML https://code.google.com/p/eac-graph-load/
simple JSON access to tinkerpop graph on backend with javscript
on front end in live prototype [current demo uses Dracula Graph
Library]
graphML file with open license should be viewable in other tools

19. Linked Data / Open Data
RDFa owl:sameAs links to VIAF
httpRange-14 (XTF URL + “#entity” for the car)
HTML5 microdata chronology
Future: RDF Dump with an Open Data License
based on Ed Summer’s “snac hacks” post
