With Apache Jena, we can generate FOAF file like this:
model.createResource("http://example.org/alice", FOAF.Person)
.addProperty(FOAF.name, "Alice")
.addProperty(FOAF.mbox, model.createResource("mailto:alice#example.org"))
.addProperty(FOAF.knows, model.createResource("http://example.org/bob"));
I want to generate a SOAF file (extension of FOAF).
Is there any method or API to do this?
Jena has a utility "schemagen" that generates vocabulary files from RDFS. It is how FOAF.java is made. There is nothing special about vocabularies, they don't have to be installed specially in a particular package. Make a SOAF.java and compile it into your program or look at FOAF.java.

As we all know,joern can easily analysis project written by c/c++,and it will generate CPG(code property graph).
Now I hava 2 csv file(nodes.csv and rels.csv),the 2 csv file can build AST(abstract syntax code)by neo4j and it can be shown in neo4j.But AST is not enough for me,what i need is CPG.How could i use the 2 csv file to build a CPG and show it in neo4j.I wanna to know how to use joern to make my ast'csv file become cpg'csv file.Or you hava other ways to make me do this.
I relly need your help,please.Thank you very much.
Avro's IDL page documents that avro-tools.jar has an idl command converting an avdl file to an avpr file. Is there a way to go in the other direction, from an avpr file to an avdl file?
I was unable to find any documentation on this matter but given that the two formats appear to contain the same data with different syntax, it should be possible to convert both ways.
I have written a java util to create a IDL from a bunch of avro schemas, part of spf4j-avro for more detail see. Makes schemas a lot more readable...
As a ace framework newer, i always encounter some problem when using this framework.
I copy some example code from website and execute it in linux. however some error throw out because of no include correspond header file. for exmaple some error like this: error: ‘sleep’ is not a member of ‘ACE_OS’.
so how can i found this function define in which header file
Most easiest is just to do a "grep sleep $ACE_ROOT/ace/OS*.h", that tells you the file where this method is defined. Other option is to use the most recent doxygen tree at http://doxygen.theaceorb.nl/libace-doc/index.html
I'm building an ASP.Net MVC4 application and the customer wants to be able to supply an XML configuration file, to configure a vendor list in the application, something like this:
<Vendor>
<Vendor name="ABC Computers" deliveryDays="10"/>
<Vendor name="XYZ Computers" deliveryDays="15"/>
</Vendors>
The file needs to be dropped onto a network location (i.e. not on the web server) and I don't have a database to import and store the data.
The customer also wants the ability to update it daily. So I'm thinking I'll have to do some kind of import (and validate the file) when the application starts up.
Any good ideas on the best way to accomplish this?
- The data needs to be quickly accessible
- Ideally I just want to import/store it once, or be able to access it quickly
- I need to be able to validate the file, so it might be prudent to be able to be able to switch to a backup
One thought was to use something like Entity Framework and simply read the file whenever I needed it, but if possible I'd hold it in memory in the application if possible.
Cheers

No need to import it into a database or use Entity Framework. You can simply use .NET Xml Serialization to accomplish this.
The command line tool xsd.exe will generate c# classes from your Xml file. From the command line:
xsd.exe myfile.xml
xsd.exe /c myfile.xsd
The first command will infer and create an xml schema file (myfile.xsd) from your xml. The second command will convert the schema file to c# classes.
Then use the XmlSerializer class to deserialize your xml file into objects (assuming multiple objects in one file):
MyCollection myObjects= null;
string path = "mydata.xml";
XmlSerializer serializer = new XmlSerializer(typeof(MyCollection));
StreamReader reader = new StreamReader(path);
myObjects = (MyCollection)serializer.Deserialize(reader);
reader.Close();
You can use the .xsd file generated above to validate your xml files. Here's a link showing how: http://msdn.microsoft.com/en-us/library/ms162371.aspx.
Something that I've had a good hard look for and I have not been able to find, is how to efficiently obtain a hard copy of Javadocs? Obviously, one solution is simply to navigate to each page and execute a browser print, but there's got to be a better way! Do you guys have any ideas?
You can use DocBook Doclet (dbdoclet) to create DocBook XML from your JavaDoc Comments. The DocBook XML can then be transformed to PDF or (Singlepage-)HTML.
You can call the tool from the commandline. Point it to your class files and it will generate the DocBook XML. This works similar to the javadoc command which will generate the JavaDoc HTML. Example:
./dbdoclet -sourcepath ~/my-java-program/src/main/java -subpackages org.example
The result is a DocBook XML file in a dbdoclet subdirectory which can be used to create a PDF or HTML file. This can also be done from the command line; I am using the docbkx-maven-plugin for this.
You can do mass conversions with it, but it would require some time to make it work the way you want.
