Apache Jena Reviews & Product Details

it is a open source Semantic Web framework that is more reliable anyone can contribute and modify because it is open source Review collected by and hosted on G2.com.

it take some time to setup and need more community support Review collected by and hosted on G2.com.

Apache Jena is an open source semantic web framework for Java. It provides an API to extract data from and write to RDF graphs. This is the attractive part of Apache Jena.The graphs represented as an abstract model. A model can be sourced with data from files, Databases, URLs or combination of these.

Apache Jena is mainly for extract data and pushes this data to graphs or models. So we need to familiar with these technologies. Review collected by and hosted on G2.com.

It's completely FREE as open sourced Java-based software from Apache Software Foundation. It includes a majority of semantic web technology standards, such as RDF API, SPARQL query language, and Ontology API. Review collected by and hosted on G2.com.

Some of the integration and version upgrades and compatibility issues are difficult at times to manage. Review collected by and hosted on G2.com.

I've used a lot of paid and free RDF/LD/triplestore tools and I appreciate that jena is easy to install, and is updated all the time. Fuseki is pretty easy to use, and the tools all are very well maintained Review collected by and hosted on G2.com.

Unfortunately, Java - certainly it is nice it runs everywhere but it's just not what everyone expects in 2018, esp. with how every server does not have jdk 1.8 so you have to install it. Fuseki doesn't really work well with large triplestores, so you eventually have to switch to a commercial product. Review collected by and hosted on G2.com.

Using Apache Jena has helped quell my fears about DB engines:

- what do when there are more data than it can fit in memory?

- do you need to allow others to make queries against your data over a network?

Jena takes care of these two items with you worrying about data. Review collected by and hosted on G2.com.

There is a lot of semantics around Jena. Apache Jena is a powerful RDF toolkit that offers many features to manipulate and query linked data. It's a powerful and versatile RDF library. However, it's not a standalone application like Marmotta. Review collected by and hosted on G2.com.

It’s very helpful in the office and it’s very reliable Review collected by and hosted on G2.com.

At first it can be complicated to download and work but after a few tries it’s easy Review collected by and hosted on G2.com.

I use it for Semantic Scripting in RDF and XML and Sparql queries in command line. It works well and has good promise for next gen web capabilities. Review collected by and hosted on G2.com.

There’s not much to dislike. It does what it is supposed to do. It uses command line and the software downloads to sit in your files. This was difficult to set up at first. Review collected by and hosted on G2.com.

I like the fact its an open source semantic web framework for java. Review collected by and hosted on G2.com.

Sometimes its hard to understand the graphs Review collected by and hosted on G2.com.

Apache Jena is a good open source tool that will provide you a decent api to extract rdf data. Review collected by and hosted on G2.com.

Because it is java and not everyone uses java in my line of work we dont see much use for Apache Jena other than the few applications we have in the lab. Review collected by and hosted on G2.com.

so basically semantic web was a dream of Tim Berners-Lee (The creator of world wide web ,and we can develop this kind of big semantic web application using java so easily using it, the best thing is we can easily define any kind of complex semantic network in it.It also has fuseki and TDB which provides very good transaction persistent layer!!The setup is not trivial for vanilla Lucene. It helps to use something like SOLR or Elasticsearch that sits on top of Lucene to allow for your applications to easily interact with the backend. SOLR provides a great API (with XML and JSON output) for indexing and retrieving data. The statistics capability are the time we used it had a lot of room for improvement. Review collected by and hosted on G2.com.

while using the logging functionality we need configure so many things so there is alwaysa new configuration overhead when you try to provide additional functionalities!! The tool that the SOLR addition of Lucene provides needs improvement, although it works and does its job and was difficult to set up and get to work in a large scale production environment.
