1. Introduction

Reference Rot

Links to Web at Large resources are subject to Reference Rot. This is a combination of two factors:

• Link Rot: Link stops working • e.g. HTTP 404 “Not Found”

• Content Drift: Linked content changes over time• Possibly to the extent that it is no longer

representative of the content that was initially referenced

2. Evidence

Articles that Link to Articles & to Web At Large Resources (PMC)

with URI references to Web at Large 156,160

over time

(b) Static contentbut very different (often

unrelated) web pages

3. Remedy

Create Snapshots of Referenced Resources

Various web archives support on-demand creation of snapshots of URIs (manual, API):

archive.today Internet Archive perma.cc webcitation.org

When creating snapshots, maintain: Original URI Snapshot URI Date/Time of snapshot

Create Snapshots of Referenced Resources

Snapshots can be created at various stages. The closer to the moment of referencing, the better the image captured.

Reference Resources Robustly

When referencing resources include:

Original URI – Allows the user to revisit the URI as it is at the time of reading, if the URI is still operational

Snapshot URI – Allows the user to visit the snapshot, if one was created, and if the web archive in which it was created is still operational

Date/Time – with the original URI allow the user to visit any snapshot created around the Date/Time in any web archive around the world (using Memento infrastructure)

Reference Resources Actionably

When referencing resources, use Link Decorations to convey Original URI, Snapshot URI, Date/Time

Robust Links Using Link Decorations, JavaScript, Memento API

Demo - http://robustlinks.mementoweb.org/demo/uri_references_js.htmlrobustlinks.js - https://github.com/mementoweb/robustlinks

Activate Robust Links

There are no Link Decorations, currently. But there is an article publication date:

Express the article publication date in an actionable manner (‘datePublished’ or ‘dateModified’ Schema.org properties) in HTML pages that contain URI references

Tailor robustlinks.js to exclude links to articles

Inject robustlinks.js in HTML pages that contain URI references

Users Follow Robust Links into Web Archives

The combination of the referenced URI and the article publication date:

Leads users to a snapshot in a web archive, created as close as possible to the article publication date

Addresses link rot

Addresses content drift

Create Archive Copies

When ingesting new content into the platform:

Parse for URI references

Create snapshots in web archives of select URIs

For these URIs, use Link Decorations in HTML to convey:

• original URI• snapshot URI • snapshot Date/Time

Users Follow Robust Links into Web Archives

The Link Decorations:

Lead users to the created snapshot, if the web archive is operational

Lead users to a snapshot in any web archive, created as close as possible to the snapshot Date/Time

Addresses link rot

Addresses content drift
