explore the search tree
with Gist, the Graphical Interactive Search Tool. Either using the built-in depth-first search strategy, or manually and interactively. Solutions and choice nodes can be inspected by clicking on them, and visualized using custom actions.
implement propagators
in Java. Whether for prototyping, for teaching, or just for fun. The propagators are integrated fully, so in your model you can mix them freely with the built-in propagators provided by Gecode.
implement branchings
for custom heuristics. Just like propagators, custom branchings fully integrate into Gecode/J.
implement search engines
using copying and recomputation. As search is fully programmable, you can write your own search engine, e.g. for LDS or A* search. In fact, Gist is implemented entirely in Java using the Gecode/J interface.

The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data.
Like the web of hypertext, the web of data is constructed with documents on the web. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML, for data they links between arbitrary things described by RDF,. The URIs identify any kind of object or concept. But for HTML or RDF, the same expectations apply to make the web grow:
1.
Use URIs as names for things
2.
Use HTTP URIs so that people can look up those names.
3.
When someone looks up a URI, provide useful information.
4.
Include links to other URIs. so that they can discover more things.
Simple. In fact, though, a surprising amount of data isn't linked in 2006, because of problems with one or more of the steps. This article discusses solutions to these problems, details of implementation, and factors affecting choices about how you publish your data.
