Semantic web \[ref\] is a W3C recommendation \[ref\] and is very useful to publish data on the web. The way this project is doing it is storing PingER data in ana Linked Open Linked standard format for data interchange on the Web. More specifically, the project is converting PingER data into a graph database in Resource Description Framework (RDF) format \[ref\]. This graph database is very flexible; the schema can be efficiently evolved with time; and the whole data can be retrieved using a Sparql Query \[ref\]. |
The advantages of putting data in this format are that since it is a W3C standard recommendation, there is a great large community familiar with it and developing researches research on it. Hence, it should be very comfortable to those people to retrieve PingER data using this method. If someone interested in the data has never heard about RDF, it is very simple to learn what is needed to use in the project. In addition, we are publishing data in a totally open format so anyone can use it. More importantly, since it is open, someone can come up with a never imagined interesting usage of the data.

Moreover, our data is being linked to many other existing datasets, such as DBPedia (a graph database for Wikipedia) \[ref\], Geonames (geographic information) [ref], and Freebase \[ref\]. The data can also be easily linked to any other existing database published in this format. The number of initiatives publishing data in this format has been growing over time so we may also find an even better and totally different usage of this project in a near future \[ref\]. The graph database is obviously internally linked with its own PingER data so we can create very specific, rich, smart, and interesting queries to retrieve data that would never (or are extremely difficult to) be retrieved without the project. |
