Definitions (en)

GeoBookmark (en)

Link (URL) which leads directly to information (e.g. an online map or a textual list) about a place and to other geo-spatial information. G. is a bookmark (favorites, hyperlinks, URLs) which points to a location aware website, like http://flickr.com/map/rapperswil !

Explanations:

• In contrast to 'normal' links which are human readable through the usual browsers these GeoBookmarks lead to internet services which are machine readable with the addition that they are location based and often also temporal based.
• Such web or mobile applications with strong geo-spatial functionality are also known as location based systems (LBS).
• A G. can also be interpreted as a "Permanent Link" which stores a user defined state (context) of a mapping application. There is a OGC standard called "Web Map Context" (WMC) which stores such information (especially for WMS clients).

Definitionen (de)

GeoBookmark

Link (URL), der direkt zu Informationen (als Online-Karte oder textuelle Liste) über einen Ort oder eine andere raumbezogene Informationen führt. G. ist ein Lesezeichen (Favoriten, Hyperlinks, URLs) zu ortsabhängigen Webapplikationen, wie beispielsweise http://flickr.com/map/rapperswil !

Erläuterungsversuche:

• Im Gegensatz zu 'normalen' Links, die menschenlesbar über verbreitete Browser aufrufbar sind, sind dies Bookmarks, die zu Internetdienste führen, die maschinell lesbar sind mit dem Zusatz, dass sie einen Orts- und oft auch einen Zeitbezug haben.
• Bei solchen Web- oder mobilen Applikationen mit ausgeprägten raumbezogenen Funktionen spricht auch von Location Based Systems (LBS).
• Ein G. kann auch interpretiert werden als "permanenter Link", der einen benutzerdefinerten Zustand (Kontext) einer Kartenapplikation speichert. Es gibt einen OGC-Standard namens "Web Map Context" (WMC), der derartige Informationen speichert (z.B. von WMS-Clients).

Use of GeoBookmarks

GeoBookmarks can be used for the enrichment of Content Management Systems (CMS) like Joomla, Drupal, Wikimedia, and Blogs and Forum Software, like Wordpress, through it's ability to integrate with Web Maps.

Use Cases for the enrichment of CMS through integration with web maps

• Add new static page via RESTfull webservice (GET/POST call)
• Adapted Error Handling (better than "Your are not allowed to view this page...").
• Embed 'GeoBookmark' coordiantes in page and/or paragraph to link to map (like Wikipedia WP:GEO template).
• GeoRSS webservice (variants: last 20 items added, all items)
• KML webservice (as network link)
• GeoBookmark URL: if called with key-value (e.g. <my_domain.com>?lat={lat}&lon={lon})

Use Cases for application web maps integrated with CMS

• Map ev. integrated directly in CMS
• Add new POI interactively: New entry link is generated (title becomes new article/static page or Wiki-URL).
• Visualization uses cases like Show POIs on Map, eventually filtered; Show POIs within bounding box on sidebar; Show POIs categories on sidebar, etc. See Google Maps API, OpenLayers.org or worldkit.org.

Alternate Usages

• Link to a location with information attached to it (as showed in WebPark).
