DBpedia.org and Freebase allow their resources to be queried through keywords.
You will be able to find the URIs of the resources you want to explore by choosing a dataset and typing at least three letters of a keyword for it.
LodLive is able to analyse and "show" RDF resources even when they are not supported by a SPARQL access EndPoint.
By entering any URI to an RDF resource, you will be able to explore contents and relationships.

LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.
The project aims at publishing the first open semantic web database for movies, including a large number of interlinks to several datasets on the open data cloud and references to related webpages.
Ordnance Survey is Great Britain's national mapping agency, providing geographic data, relied on by government, business and individuals.
Ordnance Survey has published three separate linked data resources: the 1:50 000 Scale Gazetteer, Code-Point Open and the administrative geography gazetteer for Great Britain.
DBpedia Italy is an open and collaborative project for the extraction and reuse of semantically structured information of the Italian version of Wikipedia. The project aims to enable the usability of the Wikipedia information within external software and applications.
data.cnr.it is an initiative of the Italian National Research Council aimed to provide public access to the information of the CNR organization.

LodLive project provides a demonstration of the use of Linked Data standards (RDF, SPARQL) to browse RDF resources. The application aims to spread linked data principles using a simple and friendly interface with reusable techniques.
The basic principle underlying LodLive is to prove that resources published according to the W3C SPARQL standard are easy to reach and understand, with hopes that the LodLive approach can stimulate Public Administrations and large-scale data owners to add their resources to the LOD and share them. You can start browsing by querying the endpoint for a specific resource, or start from one of the provided URI examples.
LodLive is composed of a jQuery plug-in (lodlive-core.js), a JSON configuration map (lodlive-profile.js), an HTML page, a few images (sprites), and some other jQuery public plug-ins. It is as simple as that.
When navigating the data graph, how will I know which endpoint I'm at?
By going over the resource with your mouse, a box will appear in the lower left-hand corner in which certain features will be indicated, including the resource's endpoint.
The system seems to freeze when I open certain resources, and with IE it does not seem to work.
LodLife makes full use of the computer's power that it is accessing, and this has allowed us to develop an application that does not require any server component. The application can therefore be used immediately once it is downloaded.
We recommend using a recently up-dated browser, particularly Opera,
Safari or Google Chrome; FireFox will work but with a slower navigation function; Internet Explorer does not currently work with the application because it is not capable of managing certain LodLive features and functions.

It is possible to signal an endpoint at info@lodlive.it so that it can be inserted in the application and made available at lodlive.it. Generally the best results are obtained with datasets having owl:sameAs properties towards other resources available on SPARQL endpoints.
It is important to provide as much information as possible on the resources existing in the endpoint and on the specificities of the dataset. LodLive can be specifically configured to best represent the contents that it navigates.
LodLive is an experimental project that was set-up to spread and promote the linked-open-data philosophy and to create a tool that can be used for connecting RDF browser capabilities with the effectiveness of data graph representation.
LodLive is the first navigator to use RDF resources based solely on SPARQL endpoints.
LodLive aims to demonstrate how resources published by W3C standards for the semantic web can be made easily accessible and legible with a few viable tools.
LodLive is capable of connecting the resources existing in its configured endpoints, allowing the user to pass from one endpoint to another by making use of LOD interconnection capacities.
Here you can follow the direct and inverse connections provided by the resource by moving freely from one "circle" to the others.
Every new pop-open resource will guide the user to those relating to it, automatically connecting the new "circle" to the ones they have already opened.
Every time an owl:sameAs property is reached throughout the course of navigation, LodLive will connect to the related endpoint, enabling the user to move to the new available resources within the same navigation environment.
