World Wide Web Archives Browser

This is a simple web client that exposes web archive holdings via the Memento protocol.

Given a URL, the client uses one or more known TimeGates to look up all known archival holdings, them summarizes them and provides links.

To run it, use

play run

or, if you are behind a proxy, specify the proxy server as follows:

play run -Dhttp.proxyHost=my.proxy.host -Dhttp.proxyPort=3127

To Do List

Make the urlender script more robust so it times out itself?
- See http://code.google.com/p/phantomjs/issues/detail?id=184
Add busy logos/warning while screenshots are loaded?
Add text that displays if there is no JavaScript?
No LIVE?
Fix caching so that pre-filtered results are cached instead?
Use Future pattern for long calls to avoid AskTimeoutException (see on graphs failing to load. JS?).
Allow years to be selected, in turn filtering the list of Mementos to show a year-long graph etc.
Add a lots-of-screenshots timeline. c.f. https://github.com/NUKnightLab/TimelineJS
Use timeline screenshots to estimate degree of change over time (e.g. even just colour changes).
Make screenshots cope better with none-HTML content?

Memento Issues

One minor issue appears to be that the lanl.gov aggregate TimeGate does not appear to aggregate everything. Things like individual Wikipedia pages are (e.g. ) not coming up, despite the fact they are in the UK Web Archive and indeed reported by our TimeGate. They are also clearly stored elsewhere, e.g. http://wayback.archive.org/web/*/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_is_an_encyclopedia

curl -I http://www.webarchive.org.uk/waybacktg/memento/timegate/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_is_an_encyclopedia

Leads via a redirect to the timebundle

http://www.webarchive.org.uk/waybacktg/ore/timemap/rdf/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_is_an_encyclopedia

Which is the RDF form, so need an RDF parser to extract the instances.

It appears the Aggregator is still using a proxy, so we should move Memento to production.

http://mementoweb.org/depot/proxy/BL/

curl "http://mementoproxy.lanl.gov/bl/timemap/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_is_an_encyclopedia"

Error: 404Unknown time map serialization

Note that

curl http://api.wayback.archive.org/list/timemap/link/http://en.wikipedia.org/wiki/Wikipedia:Wikipedia_is_an_encyclopedia

Works fine, so I wonder if the error on the BL proxy is throwing the whole aggregation off?
