Juni 2018 Berlin 2018 iii A Bill of Rights for Users of the Social Web Authored by Joseph Smarr, Marc Canter, Robert Scoble, and Michael Arrington1 September 4, 2007 Preamble: There are already many who support the ideas laid out in this Bill of Rights, but we are actively seeking to grow the roster of those publicly backing the principles and approaches it outlines. That said, this Bill of Rights is not a document “carved in stone” (or written on paper). It is a blog post, and it is intended to spur conversation and debate, which will naturally lead to tweaks of the language. So, let’s get the dialogue going and get as many of the major stakeholders on board as we can! A Bill of Rights for Users of the Social Web We publicly assert that all users of the social web are entitled to certain fundamental rights, specifically: Ownership of their own personal information, including: • their own profile data • the list of people they are connected to • the activity stream of content they create; • Control of whether and how such personal information is shared with others; and • Freedom to grant persistent access to their personal information to trusted external sites.

Since its beginnings in the late 1980s, the success of bioinformatics has been associated with rapid developments in computer sci- ence, not least in the relevant hardware and software. In addition, biotechno- logical advances, such as have been witnessed in the fields of genome sequencing, microarrays, and proteomics, have contributed enormously to the bioinformatics boom. Finally, the simultaneous breakthrough and success of the World Wide Web has facilitated the worldwide distribution of and easy access to bioinformatics tools. Today, bioinformatics techniques, such as the Basic Local Alignment Search Tool (BLAST) algorithm, pairwise and multiple sequence comparisons, queries of biological databases, and phylogenetic analyses, have become familiar tools to the natural scientist. Many of the software products that were initially unin- tuitive and cryptic have matured into relatively simple and user-friendly prod- ucts that are easily accessible over the Internet.

We expect the same from the apps and transport systems we use to traverse our cities on a daily basis. Do public transport sector APIs meet this new demand? A number of public transport providers have been at the forefront of the open data movement for years. Across the globe many of these transport providers now offer programmatic access to their data via REST APIs. For some, it’s been almost a decade. As hardware and software have become more sophisticated, so too have the demands Matthew O’Riordan of developers working with data of all kinds. REST APIs brought about a revolutionary change in the way organizations Founder and CEO Ably exchange data and the way in which developers create new applications and experiences. In transport, this saw the creation of CityMapper, Moovit, and many others. But REST APIs only satisfy request/response cycles and aren’t well-suited to streaming live updates to third-party apps and services when latency of updates really matters - like with travel updates. As a result of this, at Ably and across the wider realtime ecosystem, we’re seeing developers seek out Realtime APIs in many aspects of their work - largely driven by end-user demand.

  • Linked Research on the Decentralised Web
    Linked Research on the Decentralised Web Dissertation zur Erlangung des Doktorgrades (Dr. rer. nat.) der Mathematisch-Naturwissenschaftlichen Fakultät der Rheinischen Friedrich-Wilhelms-Universität Bonn vorgelegt von Sarven Capadisli aus Istanbul, Turkey Bonn, 2019-07-29 Angefertigt mit Genehmigung der Mathematisch-Naturwissenschaftlichen Fakultät der Rheinischen Friedrich-Wilhelms-Universität Bonn 1. Gutachter: Prof. Dr. Sören Auer 2. Gutachter: Dr. Herbert Van de Sompel Tag der Promotion 2020-03-03 Erscheinungsjahr 2020 Abstract This thesis is about research communication in the context of the Web. I analyse literature which reveals how researchers are making use of Web technologies for knowledge dissemination, as well as how individuals are disempowered by the centralisation of certain systems, such as academic publishing platforms and social media. I share my findings on the feasibility of a decentralised and interoperable information space where researchers can control their identifiers whilst fulfilling the core functions of scientific communication: registration, awareness, certification, and archiving. The contemporary research communication paradigm operates under a diverse set of sociotechnical constraints, which influence how units of research information and personal data are created and exchanged. Economic forces and non-interoperable system designs mean that researcher identifiers and research contributions are largely shaped and controlled by third-party entities; participation requires the use of proprietary systems. From a technical standpoint, this thesis takes a deep look at semantic structure of research artifacts, and how they can be stored, linked and shared in a way that is controlled by individual researchers, or delegated to trusted parties. Further, I find that the ecosystem was lacking a technical Web standard able to fulfill the awareness function of research communication.

  • UN/CEFACT Orchestration Eb-Mou/MG Webinar Internet of Things
    UN/CEFACT Orchestration eB-MoU/MG Webinar Internet of Things Ian Watt UN/CEFACT Vice Chair: International Supply Chain Program Development Area [email protected] UNECE – UN/CEFACT 12th. September 2018 (CET 10:00-11:30 International Supply Chain Programme Development Area Domains: (ISCO & SCM&P & T&L) ISCO: International Supply Chain Orchestration Domain SCM&P: Supply Chain & Procurement Domain T&L: Transport and Logistics Domain 2 Orchestration Domain Background Information • Over the past decades, UN/CEFACT has developed a number of standards including business process models, XML schema and core components. The general overarching technical specification of the UN/CEFACT Modeling Methodology (UMM) was intended to guide much of this work. This guidance was useful for electronic messages which correspond to complete paper documents. • Today, data exchange is being conceived as snippets of information through event-driven data exchanges instead of exchanging complete ‘document’ equivalent messages. This is evident in projects such as the Reference Data Models, the Data Pipeline, Blockchain or Internet of Things. These new methods of data exchange require new methods of considering how these exchanges can work together and complement each other for a same transaction. 3 Orchestration Domain Scope The scope of the international supply chain orchestration Domain is to support the efforts of all UN/CEFACT related projects to deliver their semantic specifications in a way that suits implementers of web platforms and pipeline /IoT projects as well as traditional document exchange projects. To achieve that, we will • Develop an architecture model that presents the Supply Chain Reference Data Model (SCRDM) and Multi-Modal Transport Reference Data Model (MMT) as a set of granular information resources with clearly defined state lifecycles • For each web resource, explore possibilities such as an Open API 3.0 specification that represents the resource as a RESTful API with JSON data payload and JSON-LD links to related resources.

These diverse interactions are based on a few key communication paradigms and protocols, honed and adapted over the past forty years to their current state as the common substrate which powers the entire Web. ››› 3 This White Paper provides an overview of these paradigms and key protocols. It collects many topics we have touched on in various PubNub blogs into a comprehensive story. This overview describes the key communications protocols developed for the Web, by open standards setting bodies like the IETF and W3C, and which are now built into operating systems or available as royalty- free, open source implementations.
