From WWW, the uncharted World Wide Web
To GGG, the charted Giant Global Graph


In the history of human mankind, map has always been of primary importance for any kind of human exploration. From the era of great maritime explorers to the era of brain and genome mapping, cartography has continually changed in order to meet the demands of map users. Nevertheless semantic and concept mapping of data on two or three dimensions has several challenging problems to attack. Naming and complexity of objects on the map, representation of relations, layout and presentation, navigation and editing, are among a few to consider.

Despite the difficulties that arise on the visualisation part of information architecture, the central issue lies elsewhere. We argue, that the cornerstone for building the next generation of information systems, including the internet, is a well defined and standardised unit that will be human readable for measurement and exchange of information. The equivalent notion of an information unit for machines is indeed one of the most impressive characteristics of our digital information age and it is based on the power of abstraction we apply to a series of two digits only, 0 and 1, in order to conceptualize visually and aurally human information processing. Files and documents, databases and programming languages, web applications and services, email and digital media, enhance the way we communicate with others. Our perceptibility for the world around us is strengthened.

In computers, information is always encoded in binary data format and it is processed accordingly. But the presentation of information to humans is dependent on the use of it. This becomes most evident when we compare a computer programmer to the end-user of an application or the web. A programmer can read and understand code in many programming languages, he can process the content of a file in many different formats. He uses various forms of symbol representation to manage information and interact with the machine. Indeed, in the history of computer science there are numerous examples of handlers that play such a role, e.g. file and folder referring to data stored permanently, URL addresses referring to web resources, primary and foreign keys referring to tables of data, names for classes of objects and their instances referring to the encapsulated data and methods.

In all cases the common ground for representation of information, the vehicle of information communication, appears to be some symbol, a"sign" according to Peirce theory, that represents the actual thing itself. Fortunately that "sign" has already been modelled in a standard way that of Topic Maps ISO/IEC 13250. Nevertheless what has not been realised so far in computer systems is the concept, i.e. topic, centric use of applications. Within this perspective there is a clear distinction between an existing digitised information resource, e.g. web document, and the abstract notion of a concept, e.g. wikipedia, where the first is linked to the second. Instead of that, proponents of semantic web contemplate linking everything as a resource. As a result we are still revolving around web documents with metadata that describe them. We can escape from this fallacy. Imagine a global network of linked topics and a tour guide from WWW to GGG, from the world of linked documents to the world of linked concepts and subjects. You journey has just begun.

Ignite Athens 2012 Event

Ignite Athens InkFactory - Panajota Kalamari Ignite is a fast-paced geek event started by Brady Forrest, Technology Evangelist for O’Reilly Media, and Bre Pettis of, formerly of MAKE Magazine. Ignite is a global event, organized by volunteers, where participants are given five minutes to speak about their ideas and personal or professional passions, accompanied by 20 slides. Each slide is displayed for 15 seconds, and slides are automatically advanced. The following presentation is my talk as a pitcher, at the first Ignite event in Athens, Greece.

Good evening, for the last three years of my life, I was giving birth to new Ideas and babies! Today we will make a quick ride into the past, present, and future of informatics world.

In 1945 World War II was ended, in the same year World Wide Web was founded. Sixty seven years later, we are still thinking in terms of linked documents and data.

We are storing documents into files and web pages. We are processing documents with myriads of formats. We are organizing them into hierarchies with folders and bookmarks. We use them to share and exchange information.

So far the digital document is the main vehicle of information exchange. In 1994 Tim Berners Lee and others gave document an address for retrieving purposes. They named it Uniform Resource Locator.

URL is still the core mechanism of WWW. It is a hyperlink between documents. The Semantic Web though, overloaded URL with identity and naming of web resources and that lead to the identity crisis.

In spite the ten years evolution of the Semantic Web, the problem is still present. Binary information resources are mixed with non-binary ones and digital realizations are confused with the actual entities they represent.

Tim O’Reilly looked at the evolution of internet from a different perspective. Web 2.0 includes social networking sites, blogs and media sharing. It offers rich user experience and participation, dynamic content, and collaborative authoring.

But Web 2.0 carries the same architectural problem as its predecessor. There is a gap between the presentation of information to the user and the representation of information for machines.

Let me start with an easy problem. What is the difference between Web 2.0 and Web 3.0? The answer is ONE, because it unifies two different perspectives: the end-user perspective and the technical-user one also known as GGG or Giant Global Graph.

In the future, the end-user will have his own decentralized, specialized and personalized eponymous social networks and portals, as well as, concepts maps to illustrate a complex problem and a new navigation and search method.

On the other hand, the technical-user will be involved with many interconnected services and each one will process data in a standard way with many different forms of input and output.

For that reason, an upper level ontology is required to provide term definitions and relations. Over the past decade many foundation ontologies appeared on scene, but none as yet has been adopted by a wide user base.

Neurorganon Upper Level Ontology is different in many aspects. Based on the topic map standard, it is very easy to extend with definitions from other languages and ontologies, including a minimal set of elements, categorized and abbreviated for memorizing.

In NULO a topic represents an information resource but there is an explicit distinction between a binary information resource and the notion of a term. In a direct analogy to URL, Uniform Symbol [emphasize] Representation is the corner stone of Web 3.0

USR references everything, including files and web pages. Therefore, NULO vocabulary includes those terms and relations between them that are necessary for auditing and annotating purposes.

Last but not least NULO intuitively suggests new ways for modeling n-ary undirected relations. It introduces the variable term and the role of attributes as arguments in a relation.

OK this is more than enough detail for the moment. Why I started all this? The first reason is my intention to organize and share my collection of bookmarks. Soon I realized that neither tagging, nor hierarchical classification was close to what I was aiming for.

The second reason is related to the MEDILIG open source project. I have studied thoroughly HLT7 models, health standards, entity-relational schemas and it seems to me that the holy grail of health information interoperability is interwoven with web evolution.

Let us recapitulate. Our trip to the mysterious world of digital information has now ended. But I urge you to continue the exploration. We all need to find a map and a compass to carry on with our journey.

With the public pre-release of NULO let us proclaim the ignition of Web 3.0 for a prosperous and effective communication. Thank you for your attention.
