Realization of Semantic Atom Blog

Web blog is used as a collaborative platform to publish and share information. The information accumulated in the blog intrinsically contains the knowledge. The knowledge shared by the community of people has intangible value proposition. The blog is viewed as a multimedia information resource available on the Internet. In a blog, information in the form of text, image, audio and video builds up exponentially. The multimedia information contained in an Atom blog does not have the capability, which is required by the software processes so that Atom blog content can be accessed, processed and reused over the Internet. This shortcoming is addressed by exploring OWL knowledge modeling, semantic annotation and semantic categorization techniques in an Atom blog sphere. By adopting these techniques, futuristic Atom blogs can be created and deployed over the Internet

Tools for a content syndication

katedra: NTI;Diplomová práce se věnuje metodám pro syndikaci obsahu. Pro syndikaci obsahu na webu se používají dva základní formáty RSS a Atom. Oba mají celkem dlouhou historii, která je rozvedena v úvodu práce. V další části se zabývám detailním charakteristikou obou formátu, jejich strukturou a popisem všech elementů a atributů. Konkrétně se věnuji formátům RSS ve verzi 1.0 a 2.0 a Atom ve verzi 1.0. Četnost použití jmenovaných syndikační formátů na webu je různá. Součástí práce jsou statistiky jejich rozšířenosti v celosvětovém i domácím měřítku. Ty jsou podloženy jak veřejně dostupnými statistikami, tak vlastnoručně získanými daty. Výstupem práce je multiplatformní aplikace napsaná v jazyce Java pro správu syndikačních formátů. Jedná se o jednoduchý editor zdrojů ve formátech RSS a Atom. Aplikace umožňuje otevírat zdroje jak z lokálního disku, tak z URL. Dále pak přidávat, odebírat elementy a upravovat zdroj v integrovaném textovém editoru. Vedle těchto základních funkcí podporuje vzájemnou konverzi formátů a export zdroje do (X)HTML.The thesis deals with methods of content syndication. The two main families of web syndication formats are RSS and Atom. Both of them have a long history which is described on the beginning of this work. In the next part I describe the structure and all available elements and attributes of the both syndication formats with a view to the RSS format in version 1.0 and 2.0 and the Atom format in version 1.0. Usage frequency of these syndication formats on web sites is various. The thesis includes a statistical data of the formats distribution at worldwide and national basis. The data are supported by public and self-obtained statistics. The output of this thesis is a multiplatform application written in Java for managing syndication formats. It is a simple editor of RSS and Atom feeds which can open these feeds from a local hard drive or from a URL. The application allows the user to add and remove elements and edit the feed in the integrated text editor. It also supports a conversion between syndication formats and export to (X)HTML

Extending Sitemaps for ResourceSync

The documents used in the ResourceSync synchronization framework are based on the widely adopted document format defined by the Sitemap protocol. In order to address requirements of the framework, extensions to the Sitemap format were necessary. This short paper describes the concerns we had about introducing such extensions, the tests we did to evaluate their validity, and aspects of the framework to address them.Comment: 4 pages, 6 listings, accepted at JCDL 201

RSS et la publication simultanée sur Internet

"La publication simultanée est un paradigme nouveau de diffusion dans Internet. Au lieu de privilégier l'aspect visuel d'une page, la famille de technologies RSS permet de communiquer la structure d'un site, en vue d'une navigation plus systématique et rapide. À l'instar du foisonnement qui caractérisait la bulle Internet du tournant du millénaire, plusieurs saveurs de cette technologie furent développées en parallèle par différents groupes. L'acronyme RSS reflète cette compétition et désigne, successivement, Rich Site Summary (RSS 0.91); RDF Site Summary (RSS 0.9 and 1.0) ainsi que Really Simple Syndication (RSS 2.0). Par ailleurs, Atom 1.0 représente un format RSS entériné par les organes de standardisation d'Internet. Sont présentés les mécanismes de publication et de compilation de fils RSS."Simultaneous publication is a new paradigm on the Internet. Instead of focussing on the visual aspect of a page, the RSS family of technologies make it possible to convey the structure of a site so that it can be navigated more quickly and systematically. Similar to the proliferation characteristic of the Internet bubble at the end of the last millennium, a number of different versions of this technology have been developed in parallel by various groups. The acronym “RSS” reflects the competition, and can mean “Rich Site Summary” (RSS 0.91), “RDF Site Summary” (RSS 0.9 and 1.0) or “Really Simple Syndication” (RSS 2.0). Atom 1.0 is another RSS format, and has been approved by Internet standardization bodies. The article presents RSS feed publication and compilation mechanisms

Engineering an Open Web Syndication Interchange with Discovery and Recommender Capabilities

Web syndication has become a popular means of delivering relevant information to people online but the complexity of standards, algorithms and applications pose considerable challenges to engineers.  This paper describes the design and development of a novel Web-based syndication intermediary called InterSynd and a simple Web client as a proof of concept. We developed format-neutral middleware that sits between content sources and the user. Additional objectives were to add feed discovery and recommendation components to the intermediary. A search-based feed discovery module helps users find relevant feed sources. Implicit collaborative recommendations of new feeds are also made to the user. The syndication software built uses open standard XML technologies and the free open source libraries. Extensibility and re-configurability were explicit goals. The experience shows that a modular architecture can combine open source modules to build state-of-the-art syndication middleware and applications. The data produced by software metrics indicate the high degree of modularity retained

A Typed Model for Linked Data

The term Linked Data is used to describe ubiquitous and emerging semi-structured data formats on the Web. URIs in Linked Data allow diverse data sources to link to each other, forming a Web of Data. A calculus which models concurrent queries and updates over Linked Data is presented. The calculus exhibits operations essential for declaring rich atomic actions. The operations recover emergent structure in the loosely structured Web of Data. The calculus is executable due to its operational semantics. A light type system ensures that URIs with a distinguished role are used consistently. The main theorem verifies that the light type system and operational semantics work at the same level of granularity, so are compatible. Examples show that a range of existing and emerging standards are captured. Data formats include RDF, named graphs and feeds. The primitives of the calculus model SPARQL Query and the Atom Publishing Protocol. The subtype system is based on RDFS, which improves interoperability. Examples focuss on the SPARQL Update proposal for which a fine grained operational semantics is developed. Further potential high level languages are outlined for exploiting Linked Data

Creating interoperability within healthcare industry

During the last decade, a number of health initiatives have been undertaken in Australia. However, Australian medical systems still suffer from the chronic problem of inability to share information essential to the health and wellbeing of patients. The major causes for this are (1) the lack of a standardized format in which patient information is being kept, and (2) the lack of infrastructure to enable sharing of the information among different organizations and institutions. In this paper we propose the use of ontologies, to enable effective translation between different EHR formats, and use of web services to enable efficient information exchange and sharing. The proposed solution has the potential to greatly improve the way patient information is being used, and consequently reduce the associated costs in both human and financial terms
