Link ? Rot: URI Citation Durability in 10 Years of Ausweb Proceedings
Link? Rot. URI Citation Durability in 10 Years of AusWeb Proceedings. Link? Rot. URI Citation Durability in 10 Years of AusWeb Proceedings. Baden Hughes [HREF1], Research Fellow, Department of Computer Science and Software Engineering [HREF2] , The University of Melbourne [HREF3], Victoria, 3010, Australia. [email protected] Abstract The AusWeb conference has played a significant role in promoting and advancing research in web technologies in Australia over the last decade. Papers contributed to AusWeb are highly connected to the web in general, to digital libraries and to other conference sites in particular, owing to the publication of proceedings in HTML and full support for hyperlink based referencing. Authors have exploited this medium progressively more effectively, with the vast majority of references for AusWeb papers now being URIs as opposed to more traditional citation forms. The objective of this paper is to examine the reliability of URI citations in 10 years worth of AusWeb proceedings, particularly to determine the durability of such references, and to classify their causes of unavailability. Introduction The AusWeb conference has played a significant role in promoting and advancing research in web technologies in Australia over the last decade. In addition, the AusWeb forum serves as a point of reflection for practitioners engaged in web infrastructure, content and policy development; allowing the distillation of best practice in the management of web services particularly in higher educational institutions in the Australasian region. Papers contributed to AusWeb are highly connected to the web in general, to digital libraries and to other conference sites in particular, owing to the publication of proceedings in HTML and full support for hyperlink based referencing. -

Web Archiving for Academic Institutions Presenter 1 Title Senior Program Manager, Archive-It Presenter 2 Title Web Archivist Session Type Workshop Abstract With the advent of the internet, content that institutional archivists once preserved in physical formats is now web-based, and new avenues for information sharing, interaction and record-keeping are fundamentally changing how the history of the 21st century will be studied. Due to the transient nature of web content, much of this information is at risk. This half-day workshop will cover the basics of web archiving, help attendees identify content of interest to them and their communities, and give them an opportunity to interact with tools that assist with the capture and preservation of web content. Attendees will gain hands-on web archiving skills, insights into selection and collecting policies for web archives and how to apply what they've learned in the workshop to their own organizations. Location KIPJ Room B Comments Lori Donovan works with partners and the Internet Archive’s web archivists and engineering team to develop the Archive-It service so that it meets the needs of memory institutions. -
Getting Started in Web Archiving
Submitted on: 13.06.2017 Getting Started in Web Archiving Abigail Grotke Library Services, Digital Collections Management and Services Division, Library of Congress, Washington, D.C., United States. E-mail address: [email protected] This work is made available under the terms of the Creative Commons Attribution 4.0 International License: http://creativecommons.org/licenses/by/4.0 Abstract: This purpose of this paper is to provide general information about how organizations can get started in web archiving, for both those who are developing new web archiving programs and for libraries that are just beginning to explore the possibilities. The paper includes an overview of considerations when establishing a web archiving program, including typical approaches that national libraries take when preserving the web. These include: collection development, legal issues, tools and approaches, staffing, and whether to do work in-house or outsource some or most of the work. The paper will introduce the International Internet Preservation Consortium and the benefits of collaboration when building web archives. Keywords: web archiving, legal deposit, collaboration 1 BACKGROUND In the more than twenty five years since the World Wide Web was invented, it has been woven into everyday life—a platform by which a huge number of individuals and more traditional publishers distribute information and communicate with one another around the world. While the size of the web can be difficult to articulate, it is generally understood that it is large and ever-changing and that content is continuously added and removed. With so much global cultural heritage being documented online, librarians, archivists, and others are increasingly becoming aware of the need to preserve this valuable resource for future generations. -
Incremental Crawling with Heritrix
Incremental crawling with Heritrix Kristinn Sigurðsson National and University Library of Iceland Arngrímsgötu 3 107 Reykjavík Iceland [email protected] Abstract. The Heritrix web crawler aims to be the world's first open source, extensible, web-scale, archival-quality web crawler. It has however been limited in its crawling strategies to snapshot crawling. This paper reports on work to add the ability to conduct incremental crawls to its capabilities. We first discuss the concept of incremental crawling as opposed to snapshot crawling and then the possible ways to design an effective incremental strategy. An overview is given of the implementation that we did, its limits and strengths are discussed. We then report on the results of initial experimentation with the new software which have gone well. Finally, we discuss issues that remain unresolved and possible future improvements. 1 Introduction With an increasing number of parties interested in crawling the World Wide Web, for a variety of reasons, a number of different crawl types have emerged. The development team at Internet Archive [12] responsible for the Heritrix web crawler, have highlighted four distinct variations [1], broad , focused, continuous and experimental crawling. Broad and focused crawls are in many ways similar, the primary difference being that broad crawls emphasize capturing a large scope1, whereas focused crawling calls for a more complete coverage of a smaller scope. Both approaches use a snapshot strategy , which involves crawling the scope once and once only. Of course, crawls are repeatable but only by starting again from the seeds. No information from past crawls is used in new ones, except possibly some changes to the configuration made by the operator, to avoid crawler traps etc. -

Tyler and Beth McNeil 615 Librarians and Link Rot: A Comparative Analysis with Some Methodological Considerations David C. Tyler and Beth McNeil abstract: The longevity of printed guides to resources on the web is a topic of some concern to all librarians. This paper attempts to determine whether guides created by specialist librarians perform better than randomly assembled lists of resources (assembled solely for the purpose of web studies), commercially created guides (‘Best of the web’-type publications), and guides prepared by specialists in library science and other fields. The paper also attempts to determine whether the characteristics of included web resources have an impact on guides’ longevity. Lastly, the paper addresses methodological issues of concern to this and similar studies. -
Adaptive Revisiting with Heritrix Master Thesis (30 Credits/60 ECTS)
University of Iceland Faculty of Engineering Department of Computer Science Adaptive Revisiting with Heritrix Master Thesis (30 credits/60 ECTS) by Kristinn Sigurðsson May 2005 Supervisors: Helgi Þorbergsson, PhD Þorsteinn Hallgrímsson Útdráttur á íslensku Veraldarvefurinn geymir sívaxandi hluta af þekkingu og menningararfi heimsins. Þar sem Vefurinn er einnig sífellt að breytast þá er nú unnið ötullega að því að varðveita innihald hans á hverjum tíma. Þessi vinna er framlenging á skylduskila lögum sem hafa í síðustu aldir stuðlað að því að varðveita prentað efni. Fyrstu þrír kaflarnir lýsa grundvallar erfiðleikum við það að safna Vefnum og kynnir hugbúnaðinn Heritrix, sem var smíðaður til að vinna það verk. Fyrsti kaflinn einbeitir sér að ástæðunum og bakgrunni þessarar vinnu en kaflar tvö og þrjú beina kastljósinu að tæknilegri þáttum. Markmið verkefnisins var að þróa nýja tækni til að safna ákveðnum hluta af Vefnum sem er álitinn breytast ört og vera í eðli sínu áhugaverður. Seinni kaflar fjalla um skilgreininu á slíkri aðferðafræði og hvernig hún var útfærð í Heritrix. Hluti þessarar umfjöllunar beinist að því hvernig greina má breytingar í skjölum. Að lokum er fjallað um fyrstu reynslu af nýja hugbúnaðinum og sjónum er beint að þeim þáttum sem þarfnast frekari vinnu eða athygli. Þar sem markmiðið með verkefninu var að leggja grunnlínur fyrir svona aðferðafræði og útbúa einfalda og stöðuga útfærsla þá inniheldur þessi hluti margar hugmyndir um hvað mætti gera betur. Keywords Web crawling, web archiving, Heritrix, Internet, World Wide Web, legal deposit, electronic legal deposit. i Abstract The World Wide Web contains an increasingly significant amount of the world’s knowledge and heritage. -
An Introduction to Heritrix an Open Source Archival Quality Web Crawler
An Introduction to Heritrix An open source archival quality web crawler Gordon Mohr, Michael Stack, Igor Ranitovic, Dan Avery and Michele Kimpton Internet Archive Web Team {gordon,stack,igor,dan,michele}@archive.org Abstract. Heritrix is the Internet Archive's open-source, extensible, web-scale, archival-quality webcrawler project. The Internet Archive started Heritrix development in the early part of 2003. The intention was to develop a crawler for the specific purpose of archiving websites and to support multiple different use cases including focused and broadcrawling. The software is open source to encourage collaboration and joint development across institutions with similar needs. A pluggable, extensible architecture facilitates customization and outside contribution. Now, after over a year of development, the Internet Archive and other institutions are using Heritrix to perform focused and increasingly broad crawls. Introduction The Internet Archive (IA) is a 5013C non-profit corporation, whose mission is to build a public Internet digital library. Over the last 6 years, IA has built the largest public web archive to date, hosting over 400 TB of data. The Web Archive is comprised primarily of pages collected by Alexa Internet starting in 1996. Alexa Internet is a Web cataloguing company founded by Brewster Kahle and Bruce Gilliat in 1996. Alexa Internet takes a snapshot of the web every 2 months, currently collecting 10 TB of data per month from over 35 million sites. Alexa Internet donates this crawl to the Internet Archive, and IA stores and indexes the collection. Alexa uses its own proprietary software and techniques to crawl the web. This software is not available to Internet Archive or other institutions for use or extension. -

Legacy publishers, as well as digital-native outlets and aggrega- tors, are beginning to adapt to this new news landscape, in part by drawing newfound value from archival stories and reusing older works. However, this trend's potential remains limited by technical challenges and institutional inertia. -
World Wide Web - Wikipedia, the Free Encyclopedia
World Wide Web - Wikipedia, the free encyclopedia http://en.wikipedia.org/w/index.php?title=World_Wide_Web&printabl... World Wide Web From Wikipedia, the free encyclopedia The World Wide Web , abbreviated as WWW and commonly known as The Web , is a system of interlinked hypertext documents contained on the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks. Using concepts from earlier hypertext systems, British engineer and computer scientist Sir Tim Berners Lee, now the Director of the World Wide Web Consortium, wrote a proposal in March 1989 for what would eventually become the World Wide Web. [1] He was later joined by Belgian computer scientist Robert Cailliau while both were working at CERN in Geneva, Switzerland. In 1990, they proposed using "HyperText [...] to link and access information of various kinds as a web of nodes in which the user can browse at will",[2] and released that web in December. [3] "The World-Wide Web (W3) was developed to be a pool of human knowledge, which would allow collaborators in remote sites to share their ideas and all aspects of a common project." [4] If two projects are independently created, rather than have a central figure make the changes, the two bodies of information could form into one cohesive piece of work.
