Wikislices
In this context, a Wikislice is collection of articles pulled from Wikipedia for the WikiReader activity on the XO. The goal is to select from wikipedia well written, structured, and cited articles while excluding the rest. The entire english Wikipedia is very large and wouldn't fit on the XO. Nor are 1000+ articles on Pokemon characters important education materials for the developing world.
Please visit the project about wikislices on the english wikipedia. For further discussion and notes, see the discussion page.
Current slices
We are planning on shipping a general collection of material with the XO. Collections could be added to a student's XO based on classroom assignments or simply a child's interest in a subject.
Common slice templates are topical wikislices from Wikipedia, resulting in books such as the "Solar system" wikijunior text and various wikireaders. Tools used to make wikislices are regular expression toolkits. See the scripts and tools section below.
Science
see also Biology and Chemistry
- An update to the Biology bundle with fungi and protists is slowly underway. Ditto an update clarifying licenses of the images (all cc-by)
- Something for a bug blitz would be most helpful, drawing on the above and related zipcodezoo and misha h's content.
Physics
A list of physics laws, terms, and principles, from Wikipedia
Chemistry
A periodic table and collection o core chemistry terms, from Wikipedia.
Health
In conjunction with other Health Content, a bundle of Where There is No Doctor is underway, with a pdf - to - html conversion care of Pascal.
How to...
A collection of projects and how-tos for children, indoors and outdoors, with limited raw materials; from WikiHow.
Needs
- naming and revising a selection - for instance, creating a wikipage that lists a set of pages (optional: revisions) to make into a bundle. as a poor example, see this old api
- finding/listing selections, something like an apt-get service for collections that have been named [and made] (optional: bundle-on-demand, if the bundling takes time; or if a named bundle invokes "get latest version" rather than "get specific revision")
- creating collections : turning a named selection into a {wikitext|mw-xml|html|pdf|docbook|txt} collection or futher an rpm/xol/ other bundle of one of the above
- reader tools : search, categorization, cookie crumb trail, &c
Pascal suggests above that making a selection is currently the 'hard' part. SJ ia not quite in agreement /yet/ since we haven't made the obvious bundles that should already be available to all, recreated every month, &c. from vetted sources.
Snapshot tools
To quickly create and revise slices, one needs
- libraries for producing different styles of wikipedia snapshots (wikitext, html, txt, pdf) from categories (special:export), topics/pages (wikiosity), and index pages (wikislices)
- libraries that can do intelligent things with metadata from history and wikimedia-commons pages
- libraries that support no-image/thumbnail/mid-res image selection
- libraries that recalculate blue v. red links given a wikislice
for Wikipedia
Specifically:
- Produce snapshots of Wikipedia by size (10MB, 100MB, 1GB, 10GB, and 100GB)
- Produce snapshots by topic (Wikiosity, categories, explicit wikislice lists)
Format conversion
There are many existing flavors/formats for bundles of wiki-subsets for offline use.
Conversion tools are needed to exchange collections between similar projects : WP WikiReaders, Wikibooks, wikipedia wikislice projects, webaroo wikislices, kiwix snapshots, schools-wikipedia snapshots, ksana snapshots, WP 1.0 revision-vetting. If this isn't possible as literal "conversion" from one format to another, index selections of articles+revisions should at least be shared.
Offline reader
Wishes:
- Something that can be served via static HTML from a webserver as a last resort. Wizzy.za currently use Andrew Cates's version for this. It has a nice portal, but fairly rudimentary index, and no search.
- NB: kiwix can't do this without its reader.
- Categories.
- Search. Linterweb have this, but it needs a special reader, and I want to serve search from the webserver. Some XML index perhaps, readable by a reader and something serverside ?
Google gears:
As a recent focal point, Zvi Boshernitzan and Ben Lisbakken have both made offline wikipedia-readers using Google Gears that are pretty fast and offer some nice features in terms of letting you select a set of articles, cache them locally, and browse an index. We talked last week about how to integrate Gears more tightly into a browsing experience, with hopes of pursuing a prototype withing a couple of weeks. It would be helpful to inform such a client with lists of good revisions of articles, such a those Martin Walker and Andrew Cates have developed for their own projects... and to plan for it to support offline editing as well as reading, using synchronization tools such as Mako's distributed wiki client.
Todo
- wikipediaondvd - define what scripts are used to produce current cd and dvd images
- crawl WP for pictures from a given XML dump. (picture dumps are tarred, making this hard, sez andy-r.)
Current scripts
Scripts that are currently used to make bundles:
PDF and single-document exports
- wiki2pdf
HTML dumps
- wikiwix export (being built) : takes in a list of wikiwix entries, outputs ?
- wikiwix interface (being improved) : allow selection via firefox plugin of a set of articles for a collection
Summaries and weight-watchers
- Summarize list : takes in a list of article titles, outputs a directory of one-paragraph html files with css. (by Zdenek, not published yet)
- Compress images : take a set of pages and images, reduce images according to a slider
- no images (remove altogether) v. hotlink images (include original thumbnail, alt text when offline)
- include first {0-10} images on a page, with metadata
- thumbnail only v. include full image (but not extra large) v. include all image sizes (full screen and more-than-fullscreen where available)
- bonus: assume local resize tool v. store 3 images for large instances
