Why?
» Problems › time-‐based media is a large and ‘lumpy’ data format, hard to analyse and even harder to share your analysis › barriers to effective (re)use of audio and video data include closed collections (IPR) and proprietary tools and formats
» Solutions › clip: virtual clips (i.e. source file URL, start and stop point) › organise: annotate and group into cliplists › share: cool URIs for sharing playable clips and cliplists

Benefits
» Bringing audio and video data ‘alive’ -‐ enabling analysis without breaking copyright or altering the data
» Streamlines workflows and facilitates collaboration
» Secure and safe -‐ respects existing access permissions to data and does not alter or duplicate the original files
» Creates opportunities for › citizen science / citizen research; user generated content e.g. crowd sourcing metadata; and user analytics

Clarifications
» Clipper is… › An online media analysis and collaboration tool for digital researchers (i.e. it supports human-‐based qualitative analysis, collaboration and sharing)
» Clipper is not… › not an online audio / video editing tool › not an online publishing or repository service › not a machine-‐based analysis tool

A Little More Tech Info
» Works client side to create HTML docs that contain the Clips, Cliplists, Annotations, etc. and stores them on a server
» Docs are stored as HTML in directories › Good for long term preservation and access
› Portable and shareable and Web2.0 friendly › No audio / video is copied – metadata only
» Doc data is also stored in database for searching and managing etc.
» Has a metadata schema editor and licence picker / editor › Easily integrated into local Data Model and Licence structures

How Does it Work?
» You create virtual clips that you can annotate using free text and share as URIs
» A virtual clip contains UG metadata & UGC: › reference to the source media file, a start and end time, title, description, keywords etc. added to classify and
retrieve clips › Annotations (textual in this phase) ‘pinned’ to the timeline – can be short or long…
» Clips and their annotations can be combined to form custom playlists called cliplists.
» Cliplists can contain clips from different sources
» Researchers create virtual clips with annotations containing their coding classifications and notes
» Your virtual clip records are stored separately to the original media files as webpages with resolvable URIs (Web 2.0 / Social Media Friendly). Data is also stored in a database for searching etc
» Every clip and cliplist has a unique and persistent data document identifier that enables you to share your clips
» Your records are stored securely and can be shared without affecting media copyright or confidentiality

Technical
» Naturally Restful (client side HTML5 code) quick and responsive
» Data is stored as json (quick, non verbose and flexible) in HTML documents
» Data can be exported in different formats – XML, CSV etc.
» Native file format is HTML…
» Clipper documents are stored in directories – each has a cool URI
» Clipper data is also stored in a database to enable searching » No media data is stored or transported – just metadata about the media and UGC
» User can move their Clipper documents easily
» HTML as native file format is good for long term access and preservation…
» Implications of HTML as native file format… › Another way to understand Clipper – a HTML publishing platform that just happens to be working
with online a/v media data, at the moment…
