"Silverpeas is an Open-Source Collaborative and Social Web Portal mainly used by our users to build an Intranet or an Extranet. The key words of Silverpeas are collaboration and social network. Atop of a collaborative bus and a social network engine, about 30 ready to use applications are freely available to share documents (EDM Electronic Document Management), to streamline project management, to manage content (CMS), and to optimize the management of knowledge and skills. Among the ready to use applications, you can find: EDM, Pictures Gallery, directories, calendars, workflow, forms, blog, wiki, forums, project management, and so on. It offers also a non-technical mechanism of delegation of rights and a powerful transverse taxonomy mechanism, that is coupled with the search engine, enable users to find rapidly the information they are looking for."

"HDF (Hierarchical Data Format) technologies are relevant when the data challenges being faced push the limits of what can be addressed by traditional database systems, XML documents, or in-house data formats. Leveraging the powerful HDF products and the expertise of The HDF Group, organizations realize substantial cost savings while solving challenges that seemed intractable using other data management technologies. Many HDF adopters have very large datasets, very fast access requirements, or very complex datasets. Others turn to HDF because it allows them to easily share data across a wide variety of computational platforms using applications written in different programming languages. Some use HDF to take advantage of the many open-source and commercial tools that understand HDF. Similar to XML documents, HDF files are self-describing and allow users to specify complex data relationships and dependencies. In contrast to XML documents, HDF files can contain binary data (in many representations) and allow direct access to parts of the file without first parsing the entire contents. HDF, not surprisingly, allows hierarchical data objects to be expressed in a very natural manner, in contrast to the tables of relational database. Whereas relational databases support tables, HDF supports n-dimensional datasets and each element in the dataset may itself be a complex object. Relational databases offer excellent support for queries based on field matching, but are not well-suited for sequentially processing all records in the database or for subsetting the data based on coordinate-style lookup."

"Introduction In the modern era, software is commonly delivered as a service: called web apps, or software-as-a-service. The twelve-factor app is a methodology for building software-as-a-service apps that: Use declarative formats for setup automation, to minimize time and cost for new developers joining the project; Have a clean contract with the underlying operating system, offering maximum portability between execution environments; Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration; Minimize divergence between development and production, enabling continuous deployment for maximum agility; And can scale up without significant changes to tooling, architecture, or development practices. The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc). Background The contributors to this document have been directly involved in the development and deployment of hundreds of apps, and indirectly witnessed the development, operation, and scaling of hundreds of thousands of apps via our work on the Heroku platform. This document synthesizes all of our experience and observations on a wide variety of software-as-a-service apps in the wild. It is a triangulation on ideal practices for app development, paying particular attention to the dynamics of the organic growth of an app over time, the dynamics of collaboration between developers working on the app's codebase, and avoiding the cost of software erosion. Our motivation is to raise awareness of some systemic problems we've seen in modern application development, to provide a shared vocabulary for discussing those problems, and to offer a set of broad conceptual solutions to those problems with accompanying terminology. The format is inspired by Martin Fowler's books Patterns of Enterprise Application Architecture and Refactoring. Who should

Bueno. Eso. Compartí el que me di cuenta que puso antes Pablo en vez del original por error, pero la idea entre ambos, si la obviedad es tolerable, es idéntica :) Está muy bien estructurado en cuanto que cada factor depende de los demás a la vez que los promueve. Permite un enfoque general que incluye prácticas de arquitectura - y de armado cotidiano de productos - que posibilitan llegar donde yo entiendo - según me voy enterando - que es el lugar a donde llegar. Sin embargo, creo que ni éste departamento en sus sistemas más nuevos cumple todos y cada uno de aquellos factores. Esto, lejos de ser una crítica, es una invitación para que revisemos si es el único método posible - cosa improbabilísima - o el mejor método - también bastante improblable - a seguir. Lo que sí sostengo como un absoluto - quien no lo haría - es que es un método practicable. Mi aporte mínimo es defenderlo como uno bueno.
