Assessing The Prevalence And Archival Rate Of Uris To Git Hosting Platforms In Scholarly Publications, Emily Escamilla
Assessing The Prevalence And Archival Rate Of Uris To Git Hosting Platforms In Scholarly Publications, Emily Escamilla
Computer Science Theses & Dissertations
The definition of scholarly content has expanded to include the data and source code that contribute to a publication. While major archiving efforts to preserve conventional scholarly content, typically in PDFs (e.g., LOCKSS, CLOCKSS, Portico), are underway, no analogous effort has yet emerged to preserve the data and code referenced in those PDFs, particularly the scholarly code hosted online on Git Hosting Platforms (GHPs). Similarly, Software Heritage is working to archive public source code, but there is value in archiving the surrounding ephemera that provide important context to the code while maintaining their original URIs. In current implementations, source code …
To Relive The Web: A Framework For The Transformation And Archival Replay Of Web Pages, John Andrew Berlin
To Relive The Web: A Framework For The Transformation And Archival Replay Of Web Pages, John Andrew Berlin
Computer Science Theses & Dissertations
When replaying an archived web page (known as a memento), the fundamental expectation is that the page should be viewable and function exactly as it did at archival time. However, this expectation requires web archives to modify the page and its embedded resources, so that they no longer reference (link to) the original server(s) they were archived from but back to the archive. Although these modifications necessarily change the state of the representation, it is understood that without them the replay of mementos from the archive would not be possible. Unfortunately, because the replay of mementos and the modifications made …
Web Archive Services Framework For Tighter Integration Between The Past And Present Web, Ahmed Alsum
Web Archive Services Framework For Tighter Integration Between The Past And Present Web, Ahmed Alsum
Computer Science Theses & Dissertations
Web archives have contained the cultural history of the web for many years, but they still have a limited capability for access. Most of the web archiving research has focused on crawling and preservation activities, with little focus on the delivery methods. The current access methods are tightly coupled with web archive infrastructure, hard to replicate or integrate with other web archives, and do not cover all the users' needs. In this dissertation, we focus on the access methods for archived web data to enable users, third-party developers, researchers, and others to gain knowledge from the web archives. We build …
An Extensible Framework For Creating Personal Archives Of Web Resources Requiring Authentication, Matthew Ryan Kelly
An Extensible Framework For Creating Personal Archives Of Web Resources Requiring Authentication, Matthew Ryan Kelly
Computer Science Theses & Dissertations
The key factors for the success of the World Wide Web are its large size and the lack of a centralized control over its contents. In recent years, many advances have been made in preserving web content but much of this content (namely, social media content) was not archived, or still to this day is not being archived,for various reasons. Tools built to accomplish this frequently break because of the dynamic structure of social media websites. Because many social media websites exhibit a commonality in hierarchy of the content, it would be worthwhile to setup a means to reference this …
Using The Web Infrastructure For Real Time Recovery Of Missing Web Pages, Martin Klein
Using The Web Infrastructure For Real Time Recovery Of Missing Web Pages, Martin Klein
Computer Science Theses & Dissertations
Given the dynamic nature of the World Wide Web, missing web pages, or "404 Page not Found" responses, are part of our web browsing experience. It is our intuition that information on the web is rarely completely lost, it is just missing. In whole or in part, content often moves from one URI to another and hence it just needs to be (re-)discovered. We evaluate several methods for a \justin- time" approach to web page preservation. We investigate the suitability of lexical signatures and web page titles to rediscover missing content. It is understood that web pages change over time …
Lazy Preservation: Reconstructing Websites From The Web Infrastructure, Frank Mccown
Lazy Preservation: Reconstructing Websites From The Web Infrastructure, Frank Mccown
Computer Science Theses & Dissertations
Backup or preservation of websites is often not considered until after a catastrophic event has occurred. In the face of complete website loss, webmasters or concerned third parties have attempted to recover some of their websites from the Internet Archive. Still others have sought to retrieve missing resources from the caches of commercial search engines. Inspired by these post hoc reconstruction attempts, this dissertation introduces the concept of lazy preservation{ digital preservation performed as a result of the normal operations of the Web Infrastructure (web archives, search engines and caches). First, the Web Infrastructure (WI) is characterized by its preservation …
