[Zoo-discuss] mimeType output

Mon Jan 20 02:52:53 PST 2014

Dear Quang,
sorry for late reply.

In the ZOO-Kernel there is no specific mimeType other than "text/xml" to specify that your result is in XML format. Furthermore, as you can see here [1] there is a specific treatment for  all mimeTypes starting with « application/ » which does not correspond to your requirement. So I think that the first step should be to try using the text/xml mimeType initially, this way you will be sure that ZOO-Kernel will understand well that you want to deal with XML content and you should not face any issue doing this.

Nevertheless, I also think that we may use something similar to what we use for the MapServer support, defining two mimeTypes, one generic mimeType sur as text/xml and the specific one, in your example it should be application/vnd.agard.xml. This way, the ZOO-Kernel will take advantage of the generic mimeType to check if it is a XML content or not and will be able to deal with the relevant mimeType transparently.

If you are interested in getting such enhancement, please let me know I can integrate this quickly I think.

Waiting for your feedbacks.
Best regards,

In some cases, for instance when you are asking for the ZOO-Kernel to store your result, the name of the stored file won’t have any relation with the mimeType you specified. You can see here how it works : [1] and how mimeType are used to define extension in the filename stored.
