E. Wilde: More Diversity in Organizing Systems

(2) Abstract

Organizing systems are necessary for any institution or individual engaging in purposeful and systematic activity. These include commercial enterprises, professional service firms, educational and research institutions, governmental agencies, … and the business people, lawyers, doctors, teachers, scientists and the other people who work for them. Can we find a robust set of dimensions that broadly applies to and differentiates organizing systems when we expand their scope beyond the traditional bibliographic and cultural artifact domains?

(5) Push Platforms

Web architecture heavily depends on pull architectures
- very useful because of caching and implementation simplicity
- limiting in scenarios where push has significant advantages
No current standard for push on the Web
- some established protocols such as XMPP (mostly point-to-point)
- push requires substantial management effort on the server side
- mobile platforms provide proprietary push services (APN, C2DM, …)
Find a push model that allows analysis and comparison
- what are the facets for describing and differentiating push services?
- what is the facet intersection of the most popular platforms/protocols?
- is it possible to create an abstraction layer for platform-independent push?

(6) Gathering Media

Many rich media streams on the Web
- variety of standards (podcasts [http://www.apple.com/itunes/podcasts/specs.html], Media RSS [http://video.search.yahoo.com/mrss], …)
- wildly different levels of sophistication
- unified access would greatly enhance reuse and repurposing
Unified metadata models for media resources are hard to define
- very different contexts for the individual models
- areas of sophistication/simplification are wildly different
- many mappings are messy and not just simple subclass/superclass relations

(7) Geolocation Metadata

Minimal standard nowadays may be GPS coordinates [http://www.w3.org/TR/geolocation-API/]
- easy to implement (embedded localization technologies and GPS)
- not always possible or meaningful (images taken on a plane)
- not always useful (landscape photography with distant objects)
More sophisticated models for spatial metadata
- orientation [http://dev.w3.org/geo/api/spec-source-orientation.html] of the capturing device
- optical information such as the focal length (some of it present in Exif [http://en.wikipedia.org/wiki/Exchangeable_image_file_format])
Sufficient IO can open the door to exciting IR
- Photosynth [http://www.ted.com/talks/blaise_aguera_y_arcas_demos_photosynth.html] starts from a simple Flickr keyword search

(8) Handling Privacy Preferences

Geolocation [Geolocation Metadata (1)] in only one piece in the puzzle
- mobile and more powerful devices mean more data and more services
- users should know what is exposed, when, to whom, and how it is used
Privacy preferences should allow users to control their data
- choices should be retained and should be reused across devices
- a privacy manager should be able to handle various privacy preferences
- Browser Privacy Mechanisms [http://www.law.berkeley.edu/10219.htm] will play an important role
- expressing privacy policies and privacy preferences needs a standardized framework
- DNT [http://www.futureofprivacy.org/2011/01/24/breaking-news-firefox-do-not-track-advances/] is the short term problem
- handling privacy preferences across devices and HTML5 APIs is the long term problem
Handling privacy preferences should be treated as an organizing system
