Heritrix Logo
Heritrix is a web crawler designed for web archiving. It was written by the Internet Archive. It is available under a free software license and written in Java. The main interface is accessible using a web browser, and there is a command-line tool that can optionally be used to initiate crawls. Heritrix was developed jointly by the Internet Archive and the Nordic national libraries on specifications written in early 2003. The first official release was in January 2004, and it has been continually improved by employees of the Internet Archive and other interested parties. For many years Heritrix was not the main crawler used to crawl content for the Internet Archive's web collection. The largest contributor to the collection, as of 2011, is Alexa Internet. Alexa crawls the web for its own purposes, using a crawler named ''ia_archiver''. Alexa then donates the material to the Internet Archive. The Internet Archive itself did some of its own crawling using Heritrix, but only on a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GNU Wget (or just Wget, formerly Geturl, also written as its package name, wget) is a computer program that retrieves content from web servers. It is part of the GNU Project.

Its features include recursive download, conversion of links for offline viewing of local HTML, and support for proxies.

Web ARChive
The Web ARChive (WARC) archive format specifies a method for combining multiple digital resources into an aggregate archive file together with related information. The WARC format is a revision of the Internet Archive's ARC_IA File Format that has traditionally been used to store " web crawls" as sequences of content blocks harvested from the World Wide Web. The WARC format generalizes the older format to better support the harvesting, access, and exchange needs of archiving organizations. Besides the primary content currently recorded, the revision accommodates related secondary content, such as assigned metadata, abbreviated duplicate detection events, and later-date transformations. The WARC format is inspired by HTTP/1.0 streams, with a similar header and the use of CRLFs as delimiters, making it very conducive to crawler implementations. First specified in 2008, WARC is now recognised by most national library systems as the standard to follow for web archiving. Software * ...

ARC (file Format)
ARC is a lossless data compression and archival format by System Enhancement Associates (SEA). The file format and the program were both called ARC. The format is known as the subject of controversy in the 1980s, part of important debates over what would later be known as open formats. ARC was extremely popular during the early days of the dial-up BBS. ARC was convenient as it combined the functions of the SQ program to compress files and the LU program to create .LBR archives of multiple files. The format was later replaced by the ZIP format, which offered better compression ratios and the ability to retain directory structures through the compression/decompression process. The .arc filename extension is often used for several unrelated file archive-like file types. For example, the Internet Archive used its own ARC format to store multiple web resources into a single file. The FreeArc archiver also uses .arc extension, but uses a completely different file format. Nintendo u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
