Hi I am new to Ontology.
How can I create .owl file using Apache Jena. Actually I have some data which I want to place in ontology .owl file but I am not sure how to create .owl file.
Can someone please point to example/url to create the ontology file using Apache Jena
Thanks in advance.

I used apache-jena-3.1.0 and JDBC to read and save XML files on a table (nodes, prefixes, quads, and trips) that was pre-made in MariaDB.
I wonder if I can make an XML file by reading MariaDB using Apache-jena.
And I wonder if I can save the stored data (nodes, prefixes, and triples) back to MariaDB in its original form (appropriate for RDB).
I am constantly trying to search for related jar or mathod.
Thank you.
Using an pan-genome building tool I've ended with a database in an unfamiliar format to me which in theory should be explorable by the Neo4j browser.
Nevertheless I can't seem to find any way to achieve so and any mention on how to do it in any bibliography besides the instructions of the manual provided by the author of said tool.
I've tried to do this using Neo4j community edition server (v. 3.5.3) with the example file same as the instructions suggest but it just doesn't seem to detect the database showing only the default one.
The mentioned part of the tutorial can be found here: https://www.bioinformatics.nl/pangenomics/manual/tutorial_part3/
So, copy the database content to the neo4j data folder. Once you have that, open the neo4j.conf file and set the following configuration:
dbms.default_database=chloroplast_DB
I am not exactly sure that is the database name, use the same name as is the database folder and then start the database.
I've looked at some plugins but no success.
I tried Export Plugin 1.6 as well but the view doesn't recognize r:.. and export:.. tags.
What is the best way to export rows of data from postgresql database into an excel file from a click of a button?
Thank you.
you could create a gsp which renders a .csv-file and set the content-type of the response to application/vnd.ms-excel within the controller.
that's the easiest way, but you will not be able to control the format of cells.
Apache POI - as mentioned by Abincepto - is another solution which is more complex but gives you full control over the generated excel file
Did you try directly with apache poi ?
From the website:
The Apache POI Project's mission is to create and maintain Java APIs for manipulating various file formats based upon the Office Open XML standards (OOXML) and Microsoft's OLE 2 Compound Document format (OLE2). In short, you can read and write MS Excel files using Java. In addition, you can read and write MS Word and MS PowerPoint files using Java. Apache POI is your Java Excel solution (for Excel 97-2008). We have a complete API for porting other OOXML and OLE2 formats and welcome others to participate.
EDIT:
Here is a tutorial: Read / Write Excel file in Java using Apache POI
and a quick guide
EDIT2:
I just found another link using Grails that could help you. The example use another library: jexcelapi
The export plugin is dependent on the resources plugin. You can add the resources plugin and try again. I use resources 1.2.8. Also you need to add this to your dependencies:
dependencies {
............
// Needed for the export plugin?
compile 'commons-beanutils:commons-beanutils:1.8.3'
plugins {
............
runtime ":resources:1.2.8"
The neo4j example data does not work in the most recent version 2.1.2 of neo4j as documented here and here. They are built for 1.9 and apparently can only be upgraded to 2.0, not 2.1. Is there a way to extract the raw data as a csv or cypher file (with a bunch of CREATE statements) from either the tarballs (which contain a graph.db, which I do not understand) or the associated github repositories (which I also do not understand)?
It's up to us to update the datasets, thanks for pointing it out, I think we'll also put them into versioned subdirectories, so it is easier to see which version they are in.
In general for small enough datasets, you can use the neo4j-shell and the "dump" command to generate cypher statements.
Also in the neo4j browser you can actually download the query results as CSV.
I also wrote a set of helper tools for the neo4j shell that allows you to export and import data as csv, graphml and other formats.
I have on the one hand a wsdl url/file and on the other hand a number of xsd schema files (are the latte called binding files?).
All of these describe a webservice that I would like to consume using jax-ws.
I understand I need to generate client stubs using the wsimport utility.
I have a requirement for one distinct package per xsd schema/binding file for the generated stubs files. The generated stubs for the wsdl would be located in another package.
Does that make sense?
Is this possible? If so how?
I am missing something?
edit: I don't fully understand the difference of intent between files generated against the wsdl and files generated against the xsd binding files as when using wsimport. Can someone please explain?

first thing the xjb files are used to resolve conflicts and customizing schemas.
You can create a distinct package for a XSD if it has a specfic namespace defined for it.
For example you need a package name like com.foo.healthcare.claims then you need to have a name space for the schema as http://www.foo.com/healthcare/claims.
