Geo (microformat)
Geo is a microformat used for marking up WGS84 geographical coordinates (latitude;longitude) in (X)HTML. Although termed a "draft" specification, this is a formality, and the format is stable and in widespread use; not least as a sub-set of the published hCalendar and hCard microformat specifications, neither of which is still a draft. Use of Geo allows parsing tools (for example other websites, or Firefox's Operator extension) to extract the locations, and display them using some other website or mapping tool, or to load them into a GPS device, index or aggregate them, or convert them into an alternative format. Usage *If latitude is present, so must be longitude, and vice versa. *The same number of decimal places should be used in each value, including trailing zeroes.''Must'' and ''should'' are used per the IETF document The Geo microformat is applied using three HTML classes. For example, the marked-up text: Belvide: 52.686; -2.193 becomes: Belvide: ; by addin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geo URI
The geo URI scheme is a Uniform Resource Identifier (URI) scheme defined by the Internet Engineering Task Force's RFC 5870 (published 8 June 2010) as: a Uniform Resource Identifier (URI) for geographic locations using the 'geo' scheme name. A 'geo' URI identifies a physical location in a two- or three-dimensional coordinate reference system in a compact, simple, human-readable, and protocol-independent way. The current revision of the vCard specification supports geo URIs in a vCard's "GEO" property, and the GeoSMS standard uses geo URIs for geotagging SMS messages. Android based devices support geo URIs, although that implementation is based on a draft revision of the specification, and supports a different set of URI parameters and query strings. A geo URI is not to be confused with the former website of ''GeoURL'' (which had implemented ICBM addresses). Example A simple geo URI might look like: :geo:37.786971,-122.399677 where the two numerical values represent lati ...

SPARQL
SPARQL (pronounced "sparkle" , a recursive acronym for SPARQL Protocol and RDF Query Language) is an RDF query language—that is, a semantic query language for databases—able to retrieve and manipulate data stored in Resource Description Framework (RDF) format. It was made a standard by the ''RDF Data Access Working Group'' (DAWG) of the World Wide Web Consortium, and is recognized as one of the key technologies of the semantic web. On 15 January 2008, SPARQL 1.0 was acknowledged by W3C as an official recommendation, and SPARQL 1.1 in March, 2013. SPARQL allows for a query to consist of triple patterns, conjunctions, disjunctions, and optional patterns. Implementations for multiple programming languages exist. There exist tools that allow one to connect and semi-automatically construct a SPARQL query for a SPARQL endpoint, for example ViziQuer. In addition, tools exist to translate SPARQL queries to other query languages, for example to SQL and to XQuery. Advantages ...

Resource Description Framework
The Resource Description Framework (RDF) is a World Wide Web Consortium (W3C) standard originally designed as a data model for metadata. It has come to be used as a general method for description and exchange of graph data. RDF provides a variety of syntax notations and data serialization formats with Turtle (Terse RDF Triple Language) currently being the most widely used notation. RDF is a directed graph composed of triple statements. An RDF graph statement is represented by: 1) a node for the subject, 2) an arc that goes from a subject to an object for the predicate, and 3) a node for the object. Each of the three parts of the statement can be identified by a URI. An object can also be a literal value. This simple, flexible data model has a lot of expressive power to represent complex situations, relationships, and other things of interest, while also being appropriately abstract. RDF was adopted as a W3C recommendation in 1999. The RDF 1.0 specification was published in 2004, th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Geographic Information System
A geographic information system (GIS) is a type of database containing Geographic data and information, geographic data (that is, descriptions of phenomena for which location is relevant), combined with Geographic information system software, software tools for managing, Spatial analysis, analyzing, and Cartographic design, visualizing those data. In a broader sense, one may consider such a system to also include human users and support staff, procedures and workflows, body of knowledge of relevant concepts and methods, and institutional organizations. The uncounted plural, ''geographic information systems'', also abbreviated GIS, is the most common term for the industry and profession concerned with these systems. It is roughly synonymous with geoinformatics and part of the broader geospatial field, which also includes GPS, remote sensing, etc. Geographic information science, the academic discipline that studies these systems and their underlying geographic principles, may also ...

GeoSPARQL
GeoSPARQL is a standard for representation and querying of geospatial linked data for the Semantic Web from the Open Geospatial Consortium (OGC). The definition of a small ontology based on well-understood OGC standards is intended to provide a standardized exchange basis for geospatial RDF data which can support both qualitative and quantitative spatial reasoning and querying with the SPARQL database query language. The Ordnance Survey Linked Data Platform uses OWL mappings for GeoSPARQL equivalent properties in its vocabulary. ThLinkedGeoDatadata set is a work of the Agile Knowledge Engineering and Semantic Web (AKSW) research group at the University of Leipzig, a group mostly known for DBpedia, that uses the GeoSPARQL vocabulary to represent OpenStreetMap data. In particular, GeoSPARQL provides for: * a small topological ontology in RDFS/OWL for representation using ** Geography Markup Language (GML) and well-known text representation of geometry (WKT) literals, and ** Simple ...

Wikivoyage
Wikivoyage is a free web-based travel guide for travel destinations and travel topics written by volunteer authors. It is a sister project of Wikipedia and supported and hosted by the same non-profit Wikimedia Foundation (WMF). Wikivoyage has been called the "Wikipedia of travel guides". The project began when editors at the German and then Italian versions of Wikitravel decided in September 2006 to move their editing activities and then current content to a new site, in accordance with the site copyright license, a procedure known as " forking". The resulting site went live as "Wikivoyage" on December 10, 2006, and was owned and operated by a German association set up for that purpose, Wikivoyage e.V. (which continues to be its representative association). Content was published under the copyleft license Creative Commons Attribution-ShareAlike. In 2012, after a long history of problems with their existing host, [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Italian Wikipedia
The Italian Wikipedia ( it, Wikipedia in italiano) is the Italian-language edition of Wikipedia. This edition was created on May 11, 2001 and first edited on June 11, 2001. As of , , it has articles and more than registered accounts. It is the -largest Wikipedia by the number of articles (after the English, Swedish, German, Dutch, French, Cebuano, Russian, and Spanish editions). History As early as March 2001, Jimmy Wales, the creator and co-founder of the original English language Wikipedia, had proposed the creation of parallel Wikipedia projects in other languages. The Italian-language version was among the first ones to be created, in May 2001. The original URL was , while the standardized ISO 639 address became active a few days later. Afterwards, Wikipedia sites switched their domains from to . The very first pages (circa five hundred) were simply untranslated copies from the English-language Wikipedia; the first edits were made from June 11, 2001, onwards. One of ...

Swedish Wikipedia
The Swedish Wikipedia ( sv, Svenskspråkiga Wikipedia) is the Swedish-language edition of Wikipedia and was started on the 23 of May 2001. It is currently the largest Wikipedia by article count with its current articles, it has a ''Wikipedia article depth'' of . A majority were generated by Lsjbot, a bot, or software application. The administrators on the Swedish Wikipedia (currently ) are elected for a fixed-term period of one year and have to be re-elected after that time. History Swedish Wikipedia was launched by Jimmy Wales on the 23 May 2001 as Wikipedia's 4th language version. The "Phase I" UseModWiki software for ''sv.wikipedia.com'' was translated by Linus Tolke and the "Phase III" MediaWiki was translated by Dan Koehl together with Johan Dahlin and Max Walter. The latter, contemporary PHP-engined MediaWiki Swedish interface premiered on ''sv.wikipedia.org'' 1 December 2002, becoming the foundation for later updates.
