IPv6 – Domain Squatting, Hijacking and Phishing
IPv6, while having lots of advantages, can be expected to bring back the old problems of Domain squatting, Domain name hijacking and phishing.
Domain Squatting (or Cybersquatting) is registering, trafficking in, or using a domain name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. Continued »
IPv6 – To Deploy or not to Deploy
IPv6 is again in the news with 8th June 2011 designated as “World IPv6 Day” as Facebook, Google and Yahoo, are joining major content delivery networks Akamai and Limelight Networks (NASDAQ: LLNW), and the Internet Society, for the first global-scale trial of the new Internet Protocol, IPv6. On June 8, 2011, these participants will enable IPv6 on their main services for 24 hours. Continued »
EMML Advanced Mashup Techniques – Part II
In this blog, listing some more techniques that enable us to create advanced Mashups using EMML.
Adding HTTP Headers to the Mashup Result
HTTP headers can be sent with a Mashup result, when the mashup is invoked. Continued »
EMML Advanced Mashup Techniques – Part I
Mashups are expected to be used by the business users directly (and not require programming skill) and the tag language EMML makes it easy to learn and use. Using the simple statements and commands of EMML, quite a few useful mashups can be created.
As usage of Mashup accelerates, the tendency to create more powerful and complex mashups would follow. Continued »
Mashup Scripting using EMML from OMA
Open Mashup Alliance (OMA) is a consortium aimed at successful use of Enterprise Mashup technologies and adoption of an open language – Enterprise Mashup Markup Language (EMML) – that promotes Enterprise Mashup interoperability and portability. EMML is an XML language to describe the processing flow for a mashup. The OMA provides the EMML schema and also a reference runtime implementation that processes mashup scripts written in EMML.

Mashups combine, aggregate and remix existing data from various sources (databases, spreadsheets, websites, Web Services, RSS/Atom feeds and unstructured sources) and deliver information in a actionable format including better visualization.
Visualization is the greatest benefit derived from Mashups and accordingly most Mashups today are hosted as Internet sites, providing visual representations of publically available data. Mashups are relevant and useful both in Consumer as well as Enterprise context. Enterprise mashups are secure, visually rich Web applications that expose actionable information from diverse internal and external information sources Continued »
Drilling deeper into KML – OGC Geographic Visualization Standard
KML is an XML grammar used to visualize geographic data in an earth browser such as a 3D virtual globe, and 2D web browser of mobile mapping applications. KML has a tag-based structure with names and attributes used for specific display purposes and a KML instance is processed by web browsers in a way similar to that of HTML or XML.
KML can be used to:
- Annotate the Earth
- Specify icons and labels to identify locations on the surface of the planet
- Create different camera positions to define unique views for KML features
- Define image overlays to attach to the ground or screen
- Define styles to specify KML feature appearance
- Write HTML descriptions of KML features, including hyperlinks and embedded images
- Organize KML features into hierarchies
- Locate and update retrieved KML documents from local or remote network locations
- Define the location and orientation of textured 3D objects Continued »
Overview of KML – OGC Geographic Visualization Standard
KML is the international standard language (actually an XML schema) for expressing geographic annotation and visualization within Internet based, two-dimensional (2D) maps and three-dimensional (3D) earth browsers (or GeoBrowsers). Objective of KML is to encourage broader implementation and greater interoperability and sharing of earth browser content and context.
KML (earlier called Keyhole Markup Language) was developed by Keyhole, Inc which was acquired by Google. Google uses KML as the file format to display geographic data in Earth browsers like Google Earth, Google Maps and Google Maps for mobile Continued »
Understanding GeoRSS – GML – Geographic Markup Language
GeoRSS is a standard for providing location information as part of a data feed. Compared to GeoRSS-Simple, GeoRSS GML (or Pro GeoRSS) goes to the next level of complexity allowing different coordinate reference systems (CRS).
According to http://www.opengeospatial.org/projects/groups/gmlwg, GML, Geography Markup Language, is an XML grammar written in XML Schema for the modelling, transport, and storage of geographic information. GML is originally based on Resource Description Framework (RDF developed by W3C) and retains many features including intelligent agents and a standard syntax for describing and querying data Continued »
Understanding Geographic Feed standard – GeoRSS Simple
GeoRSS is an open and emerging standard aimed at describing geographic information (location) in an interoperable manner so that applications can request, aggregate, share and map geographically tagged feeds. GeoRSS, derived from RSS, extends existing web feeds – rendered by aggregators and web browsers – with geographic information. Continued »
