semantics
RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.

The Friend of a Friend (FOAF) project | FOAF project
The Friend of a Friend (FOAF) project is creating a Web of machine-readable pages describing people, the links between them and the things they create and do; it is a contribution to the linked information system known as the Web . FOAF defines an open, decentralized technology for connecting social Web sites, and the people they describe. [ more... ] FOAF is part of a shift towards a Web where we can choose the sites and tools we like, without being cut off from friends who made different choices. FOAF lets you share and inter-connect information from diverse sources, move it around, and use it in unexpected new ways. [ more... ]
DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data. We hope this will make it easier for the amazing amount of information in Wikipedia to be used in new and interesting ways, and that it might inspire new mechanisms for navigating, linking and improving the encyclopaedia itself.

You don't have to load an enormous general purpose JavaScript library just for dragging and sorting. We can make drag sortable lists with GDraggableObject. Autofitting markers to the map viewport is a popular routine. This method has padding parameters for not to have markers hiding under top border or under the zoom slider. GLayers map.addOverlay(new GLayer("com.panoramio.all")); and you have geotagged photos on your map!With the JavaScript library, you need to link to the JavaScript file in your web site's HTML code, and then write code in JavaScript to create and manipulate widgets. With the HTML templates, Panoramio provides normal HTML pages that contain just one widget or a combination of them, in fixed configurations; you then add a request for one of these pages into an iframe tag in your own web site so the widget will appear inside your web site, and not in a separate page. You can also look into these HTML templates and use them as examples to understand the JavaScript library. The basic concepts in the Widget API are the request and the widget . A request specifies which photos you want to show, and a widget is a graphical element that shows the selected photos in your browser.
