Roadmap

What does the repository look like?

The OLPC repository [OR] will have three main tiers:

• Tier 1 : Material that ships preinstalled on every laptop. Within each country, 100-400MB of material will be selected for installation at the factory on the laptops. Children and teachers can change this when they receive the machines; but this material will have the widest reach, and will influence the out of the box experience for new users. Material in this tier -- software and texts -- will all be available under free content licenses.
• Tier 2 : Material that ships on every school server. This material should be reasonably free.
• Tier 3 : A national tier within each country, with all materials that are available for free to that country's laptop users.
• Tier 4 : A global tier combining the shared free materials from all national tiers.

Sources

Archives

• Museums (slow changing, l to xl items)
• Libraries (med changing, s to l)
• News collections (fast changing, xs to s)
• Publisher archives (texts, s to m)
• Stock archives (individual items, xs to s)

...digital

• GR, &c

=== games ---

• mac emulator, nes emulator, also c64, other
• ps :
• sokoban (gen)
• set (c)
• checkers [1-2], chess [2], go [2]

Static content

• Blackbox 1: demo pack
• Blackbox 2: country-specific reference pack
• Blackbox 3: manuals, bootstrapping (interface, OS hacking; accessorizing)
• Texts (with links to national standards/requirements as needed)
• Modules (indexed by subject, author, source-pool, date, metadata-size, various ratings)

Extant static repositories

• Digital libraries and archives, largely online
• Museums, largely offline
• National archives , largely offline in target countries

Creative content

Viewing

• Kibbitzing
• Metadata editing : rating, other

Tools planned : unknown; general chat, not stored as metadata

Tools needed : filesharing & metadata viewer, w/ md-editor

Authoring

• Text editing
• Image editing

  Special: for photo manipulation

• Sound editing

  Special: for human voice, sounds from nature, instrumental music

• Animation
• Video

  Special: for video shot by hand, in natural light, of people and natural and manmade objects

  Special: manipulating metadata of video and audio without changing large raw datafiles

• Overview/summary tools for the above (thumbnails, previews, fingerprints)
• See also #Publishing

Tools planned :

• chat editor. chat-graphics. some default previewing?
• text editor. previewing? equations, other embedding?
• image editor. history? sharing? thumbnails?
• csound. special filters/editors?
• helix-based vid editor? no special anim editor, no metadata-based splicing tools

Tools needed : high-level previews for many different views, audio/video thumbnailing, photo/audio/video filters for standard uses

Collaboration

• Server- or shared-versioning-based text/image/media editing
• History: one app to provide history to many other apps (journal on top of the above), or patches to each authoring/viewing tool
• Metadata: trust/experience/shared-use networks

Tools planned: wiki server option; similar option? for editors of other media; wiki-like version history for all journaled content

Tools needed: metadata tools - social networks, programmatic metric analysis, simple authorship & tagging, rating/blessing by groups (as above)

Publishing

overlay with authoring and collaboration tools; also dark content below

• Sharing/publishing tool for the above (general journal sharing extended to all filetypes)

  View : Publishing history, use tracking

• Licensing tool for publishing/viewing the above (off by default)

Tools planned: publishing flags as part of each editor?

Tools needed:

• Content managment : shared privs for publishing process (consider a private 3-person effort which can be published only by consensus, or by one of them in particular)

Dynamic content

Transactions: through what facility?

Unilateral

• Continuous inputs : time, location [network and geo], sensors [external and laptop-internal]
• Tools for queries at a distance: of sensors, databases, other machines, people
• Simulations

Networked

• Server-bsaed (see also 'collaborative authoring', above)
• Passive feedback (over the network; aggregation of default-shared properties)
• Asynchronous feedback
• Semi-synch feedback (chat, simultaneous editing)
• Synch feedback (tug of war, network mapping, 3D sound/photo creation, joint simulations)

Dark content

Backups

Note network/sharing/privacy dependencies.

Capacity of author to change privacy settings.

6-mo, 2-yr, 10-yr backups.

Compression, prioritization.

'On'line, offline

Feedback/tracking : where are backups going?

Default and DIY backup solutions.

Right to vanish? Who gets to authorize deletion?

Revisions

Network/sharing/privacy dependencies.

Default use, capacity of author to change/delete revisions.

Right to vanish? For shared content? For shared and collab-edited works? Who authorizes?

6-mo, 2-yr, 10-yr revisions.

Compression, reduction over time

Distinguishing content and metadata in revisions
