This is an on-going translation

Recién estamos desarrollando la Bolsa de Bibliotecas de la OLPC (OLPC library exchange) con el fin de ayudar a los repositorios de contenido el identificar material para la XO; y para que los grupos nacionales de académicos, maestros, chicos y padres puedan desarrollar bibliotecas con material en sus idiomas. Actualmente, las laptops traen contenido en una variedad de formatos que pueden ser probados en la XO directamente, y estamos desarrollando vistas de bibliotecas que mostrarán el material y la metadata para cada formato de manera de facilitar el agregar y mezclar nuevos contenidos.

Otras notas de lanzamiento: Notas de Demostración (sobre como hacer una demo), Notas de Lanzamiento del Hardware (B1, B2), and Notas de Lanzamiento del Software — son útilas para entender al sistema y lo que hay disponible. También hay instrucciones generales sobre como usar la Interfaz Sugar.

We are just developing an OLPC library exchange to help existing repositories of content identify material for the XO; and to help national groups of academics, teachers, children and parents develop libraries of material in their languages. The laptops currently come with content in a variety of formats that can be tried out on your XO out of the box, and we are developing display libraries that will automatically display materials and metadata for each format in a way that makes it easy to add and remix new items. Other release notes: Demo Notes (on how and what to demo), Hardware Release Notes (B1, B2), and Software Release Notes -- these are all useful for understanding the system and what is available. There are also general instructions on how to use the Sugar interface.

Tanto el software como la interfaz para la creación se encuentran en estados de prueba alfa, y recién estamos armando los vínculos con los archivos y repositorios con su propia metadata y formatos necesarios. Por favor, vea los lineamientos de interfaz y de contenido para una visión de como querríamos que se desarrollase el contenido y la interfaz sobre las laptops, y como queremos que sea la interfaz hacia plataformas y colecciones ya existentes para los usuarios de la XO.

Nos hemos concentrado en la capacidad de leer, escribir y compartir material en formatos básicos, y diseñando la interfaz para que los chicos pueden editar y navegarlas. Actualmente bajo desarrollo se encuentran una vista de la malla sobre quien esta trabajando sobre que en un dado momento, una interfaz de lectura/escritura para el material editable, y un almacenamiento distribuído de contenido; todos ellos leerán y procesarán metadatos simples que le permitirán rastrear la fuente y el historial de atribuciones del material.

The software and interfaces for creation are still in alpha test stages, and we are just forming links to archives and repositories with their own metadata and format needs. Please refer to the OLPC Human Interface guidelines and Content guidelines for a vision of how we would like to see the content and interfaces on the laptops to develop, and what we want interfaces into existing platforms and collections to look like for XO users. We have been focusing on being able to read, write, and share materials in basic formats, and designing interfaces for children to editing and browsing these materials. Components still under development include a mesh view of who is working on what at any given moment, a reader/writer interface to editable material, and a distributed content store; all of which will read and parse simple metadata that helps track the source and attribution history of materials.

Si bien la biblioteca de muestra tiene mucho material estático para sus pruebas, no son más que sugerencias de lo que puede ser creado, y como sería navegado; nuestro objetivo es ayudar a los chicos y maestros a que creen sus propias bibliotecas—e identificar el material que exhibe su construcción, y por lo tanto, sean piezas interesantes para trabajos futuros.

Si Ud. crea sus propios materiales y biblioteca, o la prueba en un dado ambiente, por favor avísenos así podemos mejorarlo.

While the sample library has many static sample materials for use in testing, these are intended as suggestions of what might be created, and how they might be browsed; our goal is to help children and teachers create their own libraries - and to identify materials that expose their construction, and that can be useful pieces in later work. If you create your own library sections and materials, or test it out in a particular setting, please let us know so that we can improve it.

Introducción

Algunos materiales estupendos han sido desarrollados pero no incluidos en las imágenes de la laptop; ya sea por su tamaño, o porque requieren de software aún no incluido en las imágenes. Nos hemos autolimitado en muestras de hasta 80MiB. Una buena biblioteca incluirá secciones introductorias, paso-a-paso (how-tos), proyectos & manuales; código de muestra, colores, sonidos, formas y tipografías; juegos y actividades, referencias de bolsillo e imágenes; música, libros de audio, y videos; textos de muestra, incluyendo material para idiomas, matemáticas, y ciencias.

La última versión estable es el build 303, con firmware Q2B61. Por favor actualicen al el firmware a Q2B84 de todos modos.

La versión candidata a ser lanzada para la próxima versión estable es build 368, con firmware Q2B85. Las notas de lanzamiento abajo se aplican a dicha versión candidata.

Some great materials that have been developed are not linked from the laptop images; either because they are large collections, or because they require software not yet shipped with our builds. We limited ourselves in the latest build to 80MB of samples. A good library will include sections for bootstrapping, how-tos, projects & manuals; sample code, color, sound, shapes, and fonts; games and activities; pocket reference works and images; music, audiobooks, and video; and sample texts, including language, math, and science materials.

The latest stable build is build 303, and firmware Q2B61. Please upgrade your firmware to Q2B84 all the same.

The current release candidate for the next stable build is build 368, with firmware Q2B85. The release notes below apply to this release candidate.

Cosas que quedaron afuera

Hay material desarrollado específicamente para las próximas pruebas que serán distribuídas en los servidores escolares y no en el build; unas pocas que serán añadidas a la próxima versión estable cuando dispongamos de más espacio para las bibliotecas de muestra.

There were materials developed specially for the upcoming trials which will be distributed on school servers and not in the build; and a few that will be added into the next stable build when we have a bit more space for the sample library.

Material en camino

La biblioteca de muestra en la XO es solo un ejemplo del material que las personas estan desarrollando para nuestro intercambio bibliotecario abierto (open library exchange). Algunos de los proyectos desarrollando sus propios materiales y colecciones para la XO y lo que planean poner en línea para descargar:

• Real Networks y el equipo open-source de la Universidad Oregon State han desarrollado una Actividad Helix que se instala en tres pasos y puede utilizar casi cualquier media y formato.
• El ICDL esta preparando más libros de cuentos dibujados — algunos con el texto separado de las imágenes, para realizar búsquedas y adaptaciones locales.
• Una mayor colección en múltiples idiomas de la Biblioteca Mundial Digital (World Digital Library) (estarán lanzando una biblioteca en múltiples idiomas durante este invierno del sur (verano del norte); el material para la XO llegará en etapas).
• La actividad de cuentacuentos de UNICEF, aplicaciones de educación y mentores, todos proyectos colaborativos en-línea con trabajo-sobre-la-XO limitado — que esta siendo usado hace algunos meses sobre varias plataformas a lo largo de Africa.
• Videos para chicos — tanto creados sobre-la-XO y convertidos a partir de los archivos fílmicos.
• Los desarrolladores están trabajando para lograr que paquetes tales como GCompris y PyGame funcionen en la XO.

The sample library on the XO is only an example of the materials people are developing for our open library exchange. Some of the projects developing their own XO materials and collections, and planning to make them available online for download:

• Real Networks and the Oregon State open source geam has developed a Helix Media Activity that installs in three steps and can play almost any media format.
• The ICDL is preparing more picture books -- some with text separated from the images, for searching and localization
• A larger multilingual collection from the World Digital Library (they are launching an entire multilingual library over the summer; materials for the XO will come in stages)
• UNICEF's village storytelling activity, mentoring and education apps, all online collaborative projects with a limited on-xo activity component -- being used over the next few months on many platforms across Africa
• Children's videos -- both created on-XO and converted from archives
• Developers are working to get packages such as GCompris and PyGame working on the XO

Biblioteca de muestra

The current build ships with a small set of activities (paint, blockparty, slideshow, abiword, a newsreader, etoys, a browser, xbook, a calculator, tamtam, a camera app) and materials that ship with the laptop.

The sample library is currently divided into sections that are intended to be filled up with material created and downloaded by children and teachers in each country. Its materials currently include books, images, music and sound, javascript activities, and hooks into collaborative projects and open content projects online. The journal, when complete, will provide a similar interface and replace this browser view of the local library; a similar browser-based view will continue to be available to people without XOs looking at collections of materials for the project. The current sample library is mainly in English and Spanish, with Arabic and Portuguese materials; other materials in the latter languages, as well as in Urdu and French, will be available soon.

libros & referencias

Including picture books, reference materials such as a picture dictionary or children's encyclopedia, stories and language learning materials. Works here are drawn from the International Children's Digital Library, Wikipedia, BookBox, and the Logos dictionary and children's library.

matemáticas & ciencias

Including math games, biology overviews, a periodic table, astronomical charts, or other similar matter. Work draw from Frans Lanting and the E.O. Wilson Foundation.

imágenes & mapas

Including maps of the world, images of animals, the planet, and the skies, and photographs from museums and cultural collections. With works from the World Digital Library consortium.

música & video

Including sound and music files, audiobook recordings, animations, video taken with the XO camera, simulations, laptop screencasts, and movie or television clips.

actividades

Including the software activities on the XO, intros to using the XO, projects to work on for children or their families, and games of all sorts -- constructive, solo or networked. Includes eToys and Javascript games, and how-tos from WikiHow. should include links to Block Party as well, once that is enabled.

enlaces de red

With a list of search engines (starting with Google) and a select group of links (waiting for another refining pass before adding to the build).

uniwiki

A set of projects sponsored by UNICEF, in search of a better name... 'uniwiki' is only temporary. The projects include a water & environment project to share information about improving water quality and the enviornment in one's town, a village-storytelling activity that involves taking photographs and video recordings of oneself and one's family, an HIV/AIDS outreach project, a mentoring project that pairs mentors with children from their homeland, and a self-directed education project especially for children in post-conflict regions. These are being developed in Spanish and in English.

taller sésamo

A collection of videos from Plaza Sesamo, Alaa Simsim, Takalani Sesame, and other sesame series, each scheduled for use in demonstrations in April.

Biblioteca escolar

There will be school and regional libraries that feed the individual XO libraries, and that eventually provide a way to pull down and push up modules as a child finds new interesting things or loses interest in older ones. We are developing a better idea of what the school libraries will include in each country, based on discussion with local teachers and groups. Among other things, these libraries will have larger collections of PDF and HTML and spoken books, global and stellar maps, television and other videos, cartoons, music collections, and images; as well as multilingual Wikipedia and dictionary snapshots. Suggestions for school library contents and priorities are always welcome, as every use case helps us test another aspect of the distributed network. A good place to leave these notes is on the library page.

Mapas

Maps from NASA's world satellite map collection (O(1TB) in all), the Rumsey collection (15,000 historical maps), and of space, thanks to Hubble and other massive telescopes, are all available. Suitable subsets can be cached on each school server. A tiered map distribution system will need to be set up to properly allow for map queries to pull down details around a region of interest, and push up geo-annotated data.

Video

Media collections from science and documentary archives, and from children's television programs such as Plaza Sesamo, belong on school and regional servers. In general, full-length films and longer television episodes will be streamed to an XO from a school library or other server.

Libros

Collections of books matched with a specific reader -- pdfs with the xbook activity, crossmark books with the ejohn ebookreader -- will be distributed across a school. Larger collections will be stored on the school library; on of the small servers can hold 10,000 books.
