Joel Matthew Sciamma Director – VantagePoint Cartographics Ltd. Surrey, UK Due to the paucity of deep linking between the data sources that I use, it was necessary for me in the 90s to develop a system of UUIDs that could be embedded within any type of document but, by necessity, required a search to reveal them. Better than nothing. That at least allowed the emergence of a supra-level of understanding of my data, which this manifesto now seeks to enable in a far more practical way. For those developers that understand the richness and value that support for this concept grants to all users, thank you. For OS and application developers yet to embrace these enabling facilities, imagine how much more valued your platform or product could be when part of a web of interlinked knowledge.

Dr. Jeff Hester Professor Emeritus, Arizona State University / Currently coach, consultant, and author Gold Canyon, Arizona Prior to seeing the Manifesto I was already in contact with a number of software companies making exactly this complaint.

The work that I do is creative, and draws on information from the web, journal articles, books, data repositories of various sorts (image, video, numerical data sets), numerical analysis (mine and that of others), and on down the list. My projects range from running group programs, to coaching, to writing journal articles, to a magazine column that I write, to analysis products, to video publications, to software development, to a book project that I am currently working on, and so on. That book project draws from and integrates data from an extremely wide range of fields and sources. Pouring through material generates large volumes of notes, references, and content of numerous types, much of which is likely to be used in a number of different contexts. This is, of course, in addition to finances, communication with clients and collaborators, personal projects and the like.

In short, like a growing number of professionals I am a 21st Century information worker and creator.

In my world it is absolutely impossible to simply group information according to where it will be used. One of the largest single tasks that I have — and certainly the task that brings with it the greatest friction in my productivity — is keeping things in order. Having to put a lot of effort into tracking things down, or moving/copying things from one context into another, can become the sort of overhead (both temporal and psychological) that can easily derail my work.

The only viable solution for me is to keep information in appropriate repositories, and then link into that information from numerous interdependent projects. Custom URL schemes (and to a lesser extent APIs suitable for app automation) are the foundation of that linking. Give me an app that supports custom URLs, especially deep linking into content, and I will integrate it into my world. On the other hand, an app might be the most beautiful, powerful, and unique piece of software on the planet, but absent linking it will squarely in the way of my productivity.

The internet changed the world by providing a system of deep linking within and among a huge variety of different sources and types of information. The single essential component needed for the internet to exist are web URLs. It is far past time that communication between apps within our individual worlds is as straightforward as communication with the outside world.

Gerrie Shults Retired Software Engineer San Diego, CA, USA “Aptly-placed links” do much more than reduce the cognitive load for accessing direct relationships. Through indirect relationships, they also enable the rapid recognition or construction of mental models of the larger context(s) in which the original information exists or could exist.

Stephen Millard Consulting Manager (IT)/Habitual Automator of Computers and Efficiency Advocate York, UK Ease and reliability of access to information are what modern society is built upon from the Information Age. As we progress more deeply into an age of knowledge management and creation on a personal, group, and even societal level, we need to ensure an architecture is in place to support this. The Manifesto for Ubiquitous Linking sets out a clear and logical foundational component for this architecture. I hope to see both the support for and the delivery of the tenants of this manifesto increase, in time creating a greater capability and potential for more digitally integrated learning opportunities.

Tomáš Baránek book publisher / lifehacker / blogger / linker Brno, Czech Republic
Chuck Wade Principal Consultant Hopkinton, MA, USA Knowledge is as much about the threads (read “linkages”) that connect sources of information as the information itself. Instead of trying to corral information behind proprietary fences, application developers, information purveyors, software infrastructure maintainers, and the media at large should be facilitating open APIs that allow anyone to create and maintain their own links to information, as well as using the links provided by others. Ultimately sharing knowledge is really about sharing the links to information. I avoid using social media, in part because the major players in social media have been focusing on trying to make their platforms the center of the “metaverse.” I favor being able to make and maintain my own linkages, instead of relying on profit-oriented big-tech players who often exploit their customers desires to share in ways that benefit social media players at scale, while putting individual privacy at risk.

Lack of linking compromises efficiency, leads to avoidable repetition and wasted time, potentially wastes data (which in clinical settings is unethical) and most importantly, may lead to harm that could have been prevented with easy, quick access to linked data.

Rachael Gresham Manager/Developer of Student Systems Utah I would love to have this functionality so I can better support my students and staff. I rely heavily on my task manager to keep me organized, and the inability to add emails to my task manager is severely impactful.
Ellane Weedon Director Australia One day we will look back on a world without ubiquitous linking as the dark ages of knowledge management. This is not a nice-to-have; it is—it should be—the very foundation of every digital endeavour. It’s hard to mobilise a collective mindset when things have been disconnected for so long; the task now is to convince more people who have the power to bring about this change that it really is broke, and we really do need to fix it. To those of you frustrated that the masses can’t see this issue clearly, take a look in any shoe shop window, and at your own feet: shoes have been causing more problems than they solve for hundreds of years now. Still, when people who are enlightened band together, there’s always hope! —For a connected digital world, and for healthy feet.

Kirby Krieger Artist Pittsburgh, Pennsylvania, USA Hookmark should be an OS-level utility. Every application that runs on the OS should be Hook enabled. Personal computing got swallowed by the iPhone and its ilk. The long arc has been terminals to workstations back to terminals. We now sample information from multiple devices in multiple locations. Information – data in a properly formatted information carrier – has become without-location (alocative) but addressable. This is an enormous human problem: we retrieve things by indexing where we put them – by location – by context – not by their address. Alocative information results in, as described, a breakdown in cognitive facility. Computers are not like us. They do not remember where things are by context. They index by addresses. I can bring to mind almost every single house on the very long cul-de-sac where I grew up; I know only one address, mine, which I was forced to memorize before I was allowed to go outside by myself. On our personal computers, we created context for our information. Personal computing in that sense is gone; that context-making is almost certainly gone as well. We might be able to replace locative memory with a personal branching trail system of “hooks” anchored in properly-formatted information carriers. (We might, and I think the possibility is real and disturbing, just make a mess.) Instead of filing something you want to retrieve later, you hook it. You don’t need to remember where it is, you need to remember the context you’ve given it. We remember contexts. Context is a good human index for information retrieval. My hope is that this returns the personal to computing, but whereas one once controlled one’s own single machine and stored things where one could find them, one now, across the entire expanse of digitized information, grows and controls one’s personal Hookery and uses that on any device to retrieve what’s on one’s mind, quickly. The Hookery becomes what the once-vaunted “desktop” never was. Hookeries ASAP, and thanks.

Skybird Stout Founder Seattle, WA Deep linking represents a foundational paradigm shift for neurodivergent individuals who wish to interact with computers in a non-linear way if needed. Cognitive wiring differs from one individual to another, but without adapting to the changing awareness embedding itself within the cultures of a more diverse and interconnected society, those of us who should not be required to fit ourselves into expected patterns should be able to make technology adapt to us, not the other way around. Deep linking presents a way to unify the digital asset collections we tend to accumulate, and by empowering people of all cognitive styles to make a system that works for them, we can make a difference in quality of life.

Technology was made for the sake of man, not man for the sake of technology.
Tim Fallon Postdoctoral Fellow University of California, San Diego Using PDF deep linking has changed my scholarly life. The whole software world needs to get on board with deep linking.
Austin Otto Educator Sacramento, CA
Andres Leon-Geyer Researcher and Professor Peru Open standards and interoperability not only are necessary to foster equity between diverse contexts of economical power and technological development (and to reduce the digital gap). Human knowledge itself is based on the work of others, and consequently its interconnection means its development. If we dont foster interoperability and free access to all resources, we create an obstacle to our own development as cultures.
Gregor Rosenauer Software engineer Vienna, Austria As a big supporter of open source, open data formats and interoperability, and as a signee of the data centric manifesto, deeply rooted in Unix philosophy of single purpose tools connected through pipes and filters, I’ve already enjoyed back in 1997 through BeOS what a modern, open, metadata driven system could be like, and in 2003 started to work on an idea to add relations.
Now, 20 years later, I’ve finally found time again to realize this vision in the form of SEN, adding semantic extensions to Haiku, the open source successor of BeOS, and I’m glad to see all the interest and movement towards deep linking information on desktop filesystems.
Glad to support this manifesto, too.
Vatsal Manot Founder San Francisco
David Topps Professor University of Calgary It is high time that this became commonplace functionality on a wide range of connected web apps. We have had limited cross-linking in the past but too many large corporations have attempted to corral us into using their monolithic suites.
