[Geoserver-users] isDynamic in info.xml

Thomas_Zuberbuehler1 · February 1, 2007, 10:53am

Hey there

A short question.
What is the function of the parameter isDynamic in info.xml?

Thank you.
Regards,
Thomas

I'm not sure. I don't have that parameter in any of my info.xml files.
Does your file contain a custom schema, or anything out of the ordinary?

Is it causing issues for you or are you just curious as to what it is doing?

Brent, thank you. That is correct, there are no isDynamic in this file. I
wrote it false and meant the parameter "dynamic". Sorry.

I try to analyze the info.xml file. What is the function of "dynamic" and
"numDecimals"?

Thomas

Dynamic is no longer used at all. I didn't realize we still had it in the sample files. It was to auto-generate the bbox, but we realized it's better to do it with the 'generate' button.

numDecimals is just for the WFS. It's not necessary, as there is a global variable that sets it. And I'm not even sure that the featureType level successfully sets numDecimals. So basically don't worry about it, it shouldn't break anything.

ah,
The numDecimals value is the number of significant figures that the data set will use. So anything beyond 8 decimal places will be rounded off.

The 'dynamic' attribute for the bounding box has always been false in the files I have seen. I will look into the code and see where it is used, but I wouldn't worry about it for now.

Yeh I think Chris is right in that the numDecimals value in the feature type is not used, and a global value is used instead.

Chris, should we remove those attributes from the config to avoid confusion? It's a toss up of whether to do it now while we are thinking about it, or do it later when we re-do our config system.

catching up on email

numDecimals were used to round off coordintates when encoding to xml (at least
on the SVG output). I'm sure once upon a time it was used for per feature
type rounding off on the WFS too. Guess WFS only uses a global value now?

anyhow, I think it's more valuable as a per feature type setting overriding
the global value?

Thank you to all of you for your great help!

I think I set default values to this parameters. There can be a xml schema
(for info.xml) useful, can't it?

Regards,
Thomas

I agree it should probably be assigned to each individual feature type. We will have to include it in the UI if we are going to use in instead of the global value however. Except it isn't even in the UI...

I will open a jira task to re-visit this for 1.6

I could be wrong, it may be per featureType. Just check the code and see.
