Free information data software for linux

Java + information flow (Jif in short) is a security-typed programming language that extends Java with support for information flow control and access control, both at compile time and at run time.

The source code for the Jif compiler and run-time system is now available for download. Jif is written in Java and is built using the Polyglot extensible Java compiler framework.

Static information flow control can protect the confidentiality and integrity of information manipulated by computing systems. The compiler tracks the correspondence between information the policies that restrict its use, enforcing security properties end-to-end within the system. After checking information flow within Jif programs, the Jif compiler translates them to Java programs and uses an ordinary Java compiler to produce secure executable programs.

Jif extends Java by adding labels that express restrictions on how information may be used. For example, the following variable declaration declares not only that the variable x is an int, but also that the information in x is governed by a security policy:

int {Alice→Bob} x;

In this case, the security policy says that the information in x is controlled by the principal Alice, and that Alice permits this information to be seen by the principal Bob. The policy {Alice←Bob} means that information is owned by Alice, and that Alice permits it to be affected by Bob. Based on label annotations like these, the Jif compiler analyzes information flows within programs, to determines whether they enforce the confidentiality and integrity of information.

Common Data Format is a self-describing data abstraction for the storage and manipulation of multidimensional data in a platform- and discipline-independent fashion.
It consists of a scientific data management package (known as the "CDF Library") that allows programmers and application developers to manage and manipulate scalar, vector, and multi-dimensional data arrays.
Enhancements:
- Adds new sets of APIs to allow Standard Interface to interact with zVariables and other CDF-related information.
- Adds MingW and FreeBSD ports.
- Adds support for Intel C++ and Fortran for Linux.
- Adds the ability to create legacy CDF 2.7 files.
- Fixes a bug that prevented directories from having .cdf or .skt extensions.

GIST is a tool kit for the rapid development of interactive web based information servers.

GIST removes the technical barriers traditionally associated with creating interactive web sites.

It has been specifically designed to allow user communities to share information and communicate more effectively without the need for a full-time technical web master.

GIST provides support for managing user definable information objects, so you dont write any CGI programs or SQL in your HTML, or worry about indexing your data: GIST does it for you.

You define your data and its structure and GIST takes care of adding, changing, deleting and indexing it, allowing you to focus on the important issues of providing the features and facilities your user community expect and demand.

Traditional approaches to web-based-publishing involve a centralised ``webmaster or group of webmasters responsible for the provision of information contained within the site and for its maintenance. As the site grows, the cost of maintenance increases.

The prototyping activities undertaken by the Joint Rresearch Center of the European Commission (JRC) provide an alternative approach to populating and maintaining a web site, in which each member of the user community is responsible for maintaining their own information. The G7/GELOS1 server is a working example of the technology involved.

GIST is an effort undertaken by the JRC to build on the success of this prototyping activity and to generalise their functionality in a reusable component library for the construction of dynamic, user community based Information Servers. GIST allows users without programming skills to create a web server with a data model and user interface of their own design.

GIST makes it easier to build an Information Server by providing the software components required for common tasks.

In particular GIST provides facilities for: submission of information by members of a user community modification and deletion of information presentation of information search and browse user registration and user interface configuration user authentication and authorisation automatic validation of user input server configuration and definition of policy rules Regardless of the style of information it contains any Information Server needs to allow its user community to interact with it; in particular to populate and maintain the contents of its information store, and to view the information contributed by other members of the community.

Search and browse facilities are indispensable for all but the smallest of databases; there is no point storing information if no-one can ever find it.

GIST ensures that users are prevented from changing information that they are not authorised to change, and that database integrity is maintained at all times.

Various configuration options are available so that the server may be tailored the server behaviour to the needs of the community; of particular note is the ability to define local policy rules to be applied when the information store is modified.

Modularized Information Environment (MIE) is a Web-based information management tool designed to meet the needs of small or medium sized organizations.

Modularized Information Environment implements user authentication, storage of settings in a database, multi-lingual support and a presentation layer API that always generates well-formed XML.

Evolution Data Server provides a single database for common, desktop-wide information, such as a users address book or calendar events.

Evolution Data Server is also a dependency of the clock applet from the gnome-applets package, 2.10 release.

Evolution provides integrated mail, addressbook and calendaring functionality to users of the GNOME desktop.

MARGO project is an Argumentation Framework for decision making. A logic language is used as a concrete data structure for holding the statements like knowledge, goals, and actions. Different priorities are attached to these items corresponding to the reliability of the knowledge, the users preferences, and the credibility of alternatives.
These concrete data structures consist of information providing the backbone of arguments. Due to the abductive nature of decision making, we built arguments by reasoning backwards. Moreover, arguments are defined as tree-like structures.
In this way, MARGO can be used as a Decision Support System, suggesting some solutions, as other classical approaches, but also providing an interactive and intelligible explanation of this choice.
Enhancements:
- In order to evaluate the previous statements, all relevant pieces of information should be taken into account, such as the likelihood of beliefs, the preferences between goals, or the expected utilities of the alternatives.
- In the previous version, these priorities were qualitatives, i.e order relations classifying the elements from the "best" to the "worst".
- However, such qualitative information is not enough in many practical applications.
- Alternatively, this version allows quantitative priorities which are expressed by a valuation function over rules, called confidence.
