How to create new annotation type to store URL links to other data?

How to create new annotation type to store URL links to other data?

Jun-24-14 18:41:14

Hi,

I am running a java application that is able to execute any commands (I am using Java OMC library: http://code.google.com/p/javaomc/)

I know that some data is stored in annotations and that there is already several types of annotation, like Diagram or Icon.

I didn't found any type of annotation that is made to add a link to a resource (an URL).

Is there any annotation type for that?
If no, is there a way to create my own annotation type?

Thanks in advance for your answers,

Aurelien

I found this document, giving the commands that I can launch: https://www.openmodelica.org/download/OMC_API-HowTo.pdf

Particularly, at the page 8, I found this method: addClassAnnotation(A1<cref>, annotate=<expr>)

I can also use :
getAnnotations(A1<cref>) to get the list of annotations
save(A1<cref>) to save the file

I tried to add the annotation: annotate=MyNewAnnotation(http://somesite.com), and it return an error
But with :  annotate=MyNewAnnotation(httpsomesite.com), it works perfectly

The problem seems to come from the"//" that is not parsed properly, what can I do to avoid this problem using //?

Will I have any compilation/simulation proble; if I add any "custom" annotations like that in my model?
(I mean as far as its name is different from any "official" annotation, of course.)

You would need to add URL's as Strings. The usual way to add URL's to Modelica models is through the documentation annotation: Documentation(info="<html><a href=\"...\">...</a></html>")

If you want a new annotation, you should make it a vendor-specific annotation:
annotation(__MyPrefix_MyNewAnnotation = "http://...")
or
annotation(__MyPrefix(MyNewAnnotation = "http://..."))

Thank you very much,

I will use one of these formats for my application
Between quotes, I can store my "//"

Just one more question...
If I store my links in the Documentation annotation, as a "html href", as you explained,
will people using OMEdit be able to see this link an click on it easily?
