WARC (file Format)
The WARC (Web ARChive) archive format specifies a method for combining multiple digital resources into an aggregate archive file together with related information. These combined resources are saved as a WARC file which can be replayed using appropriate software such as ReplayWeb.page, or used by archive websites such as the Wayback Machine. 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 (see §7.6 "revisit"), and later-date transformations. The WARC format is inspired by HTTP/1.0 streams, with a similar header and the use of CRLFs as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archive Format
In computing, an archive file stores the content of one or more computer file, files, possibly lossless compression, compressed, with associated metadata such as file name, directory structure, error detection and correction information, commentary, compressed data archives, storage, and sometimes encryption. An archive file is often used to facilitate software portability, portability, software distribution, distribution and backup, and to reduce computer storage, storage use. Applications Portability As an archive file stores file system information, including file content and metadata, it can be leveraged for file system content portability across heterogeneous systems. For example, a directory tree can be sent via email, files with unsupported names on the target system can be renamed during extraction, :v:File management#Time stamp preservation, timestamps can be retained rather than lost during data transmission. Also, transfer of a single archive file may be faster than pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ZIM (file Format)
The ZIM file format is an open file format that stores website content for offline usage. The format is defined by the openZIM project, which also supports an open-source ZIM reader called Kiwix. The format is primarily used to store the contents of Wikipedia and other Wikimedia projects, including articles, full-text search indices and auxiliary files. ZIM stands for "Zeno IMproved", as it replaced the earlier Zeno file format. Since 2021, the library defaults to Zstandard file compression and also supports LZMA2, as implemented by the XZ Utils library. The openZIM project is sponsored by Wikimedia CH and supported by the Wikimedia Foundation.

Wget
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 name derives from "World Wide Web" and " ''get''", a HTTP request method. It supports downloading via HTTP, HTTPS, and FTP. Its features include recursive download, conversion of links for offline viewing of local HTML, and support for proxies. It appeared in 1996, coinciding with the boom of popularity of the Web, causing its wide use among Unix users and distribution with most major Linux distributions. Wget is written in C, and can be easily installed on any Unix-like system. Wget has been ported to Microsoft Windows, macOS, OpenVMS, HP-UX, AmigaOS, MorphOS, and Solaris. Since version 1.14, Wget has been able to save its output in the web archiving standard WARC format. History Wget descends from an earlier program named Geturl by the same author, the development of which commenced in late 1 ...

StormCrawler
StormCrawler is an open-source collection of resources for building low-latency, scalable web crawlers on Apache Storm. It is provided under Apache License and is written mostly in Java (programming language). StormCrawler is modular and consists of a core module, which provides the basic building blocks of a web crawler such as fetching, parsing, URL filtering. Apart from the core components, the project also provides external resources, like for instance spout and bolts for Elasticsearch and Apache Solr or a ParserBolt which uses Apache Tika to parse various document formats. The project is used by various organisations, notably Common Crawl for generating a large and publicly available dataset of news. Linux.com published a Q&A in October 2016 with the author of StormCrawler. InfoQ ran one in December 2016. A comparative benchmark with Apache Nutch was published in January 2017 on dzone.com. Several research papers mentioned the use of StormCrawler, in particular: * Cra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Libarchive
libarchive is a free and open-source library for reading and writing various archive and compression formats. It is written in C and works on most Unix-like systems and Windows. History libarchive's development was started in 2003 as part of the FreeBSD project. During the early years it was led by the FreeBSD project, but later it became an independent project. It was first released with FreeBSD 5.3 in November 2004. libarchive libarchive automatically detects and reads archive formats. If the archive is compressed, libarchive also detects and handles compression formats before evaluating the archive. libarchive is designed to minimize the copying of data internally for optimal performance. Supported archive formats: * 7z – read and write * ar – read and write * cab – read only * cpio – read and write * ISO9660 – read and write * lha & lzh – read only * pax – read and write * rar – read only * shar – write only * tar – read and write * warc (IS ...

Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages.

Heritrix
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 (programming language), 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 us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Nutch
Apache Nutch is a highly extensible and scalable open source web crawler software project. Features Nutch is coded entirely in the Java programming language, but data is written in language-independent formats. It has a highly modular architecture, allowing developers to create plug-ins for media-type parsing, data retrieval, querying and clustering. The fetcher ("robot" or "web crawler") has been written from scratch specifically for this project. History Nutch originated with Doug Cutting, creator of both Lucene and Hadoop, and Mike Cafarella. In June, 2003, a successful 100-million-page demonstration system was developed. To meet the multi-machine processing needs of the crawl and index tasks, the Nutch project has also implemented the MapReduce project and a distributed file system. The two projects have been spun out into their own subproject, called Hadoop. In January, 2005, Nutch joined the Apache Incubator, from which it graduated to become a subproject of Lucene ...
