A web based Metadata Catalog Server for data description and discovery. Supports both generic and geospatial data discovery. It implements international standards (e.g. ISO19115/19139/19119, ISO19115-3, DCAT-AP, CSW 2.0, OGC API Records). It originates from the United Nations and is used by many governments as geoportal software. Active development and discussion takes place on GitHub and OSGeo Discourse. You can also connect directly with the companies supporting the...

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on...

©XSIBackup-DC is a C binary that runs in the ©ESXi shell and behaves as a backup and replica service. It follows the same principles as our previous ©XSIBackup editions, that is: a utility that runs in the hypervisor command line and accepts arguments and values stating which VMs to backup and where to copy them. It accepts local and remote SSH paths, thus you can backup and replicate VMs to local datastores or to remote repositories in any additional ©ESXi or Linux server. Download...

Slim is a data compression system for scientific data sets, a binary and a library with C linkage. Slim works with integer data from one or more channels in a file, which it can compress more effectively and more rapidly than general tools like gzip.

mediaTUM is free software written in Python for archiving and retrieval of images, documents and other research data. It was originally developed in the framework of the DFG project IntegraTUM and is continuously expanded with new functionalities as required.

gzzzzzz enlarges a given file 6 times and writes it as a gzip file. It therefor can be "decompressed" (which makes it 6 times smaller) with the standard gzip. This shows that gzip (and deflate and any compression tool that uses one of them) but also, as I expect, any other compression format can be used to augment data significantly.

TER implements the CCSDS Recommendation for Image Data Compression (CCSDS 122.0-B-1). TER also adds new features to the Recommendation. TER is designed and programmed with the aim to provide a good basis to test and develop the CCSDS Recommendation.

Multi-threaded HDF5 filter implementing the LPC-Rice codec. This lossless codec is intended to compress correlated signal data, such as image data, stored in HDF5 chunks. The codec/filter is optimized for both compression and decompression speed, but compression ratios are still comparable to JPEG-LS and CCSDS-123 codecs.

This project has been moved to https://github.com/inikep/XWRT XWRT (XML-WRT) is a high-performance XML compressor (it also works with textual files). It transforms XML to more compressible form and uses zlib (default), LZMA, PPMd, or lpaq6 as back-end compressor. It is similar to XMill, but has many improvements.

DIASER, Geo-data duplication long-term archive system & WAN vault. Manage mixed data archives generated by existing backup software. Ensure availability using commodity hardware. Retain administrative and financial control.

This project is ANDS (Australian National Data Service) funded and aims to provide a mechanism for researchers within the University of Western Australia to upload research datasets to a central petastore. It also aims to publish metadata about the datasets to RDA (Research Data Australia) so that the datasets can be discovered (and potentially shared) by searching or browsing through the ANDS website. In order to accomplish the above functionality, this project used the following open...

SEG-Y files need special compression because they don't compress well using gzip and the like. The code is cross-platform C++ using nothing else than standard system libraries. This is a spin-off from the OpendTect project (http://opendtect.org).

CADI is an implementation of the JPIP standard (JPEG2000 Interactive Protocol - Part 9). CADI includes a JPIP server, a JPIP proxy, and a JPIP Client. CADI is designed and programmed with the aim to provide a flexible framework to test and develop ne

DataFinder is a data management client developed in Python that primarily targets the management of scientific technical data. The system is able to handle large amounts of data and can be easily integrated in existing working environments.

rSIGNAL - ruby Simple Inter-Interface Generic Aggregation Layer. It allows external data sources to be aggregated, store the aggregated data and print the aggregated data out in a transformed format to a file (or integrated HTTP server) on demand.

Tools for archiving, compressing and processing XML data.

ZLib 1.2.3 wrapper for Delphi language. It works on latest Delphi 2010 too.

StormRT is a real-time multi-resolution analysis and compression package for data compression and temporal feature detection over multiple timescales.

Alternative approach to minimum redundancy coding (fixed-length) without using tree data structures. The main advantages are simplicity and flexibility.

Knowledge management tool which is primarily designed for pdf files. The tool will let the documents get tagged either automatically or manually. Within the pdf archieve, a user will be able to retrieve desired documents quickly.

This project provides an abstraction layer for archives. This project emerged from route64, and will provide a standalone archive manipulation tool for Eclipse. At first we focus on the folowing archives: zip, war, jar, ear, t64, d64, rar, tar.

VDC has been superseded by DVN: https://sourceforge.net/projects/dvn/ ---- The Virtual Data Center project is building an operational, open-source, digital library to enable the sharing of quantitative research data, and the development of distribute

Alexandria is an archive system for large data amounts. Suitable for inhomogenous collections of books, media files, art items and other artifacts. Main focus is on easy usage, small executable file and portability.

XSDB XML is to DATA as HTML is to DOCUMENT. Publish and combine data as easily as HTML format and web browsers publish and view documents. Implementations in Python, javascript, java, C#/.NET.

This is a very powerfull criptography project that basicaly can be used to transmit or store secure data and study some cipher, hash and compression algorithms to understands how it works.
