General note: some nodes begin with a lower case, and some other nodes begin with a upper case. It may be worth to clarify what is the policy for lower/upper cases. In "GML in JPEG 2000" specification, I have the feeling that lower case is used for attributes and upper case used for classes.
Page 18 said: > Figure 5 depicts the Stream MetaData schema overview. The root node > “StreamMetaData” has > two children: If I'm understanding correctly the IIOMetataFormat specification, the root node name should be the specification name. For example the root name for J2SE standard metadata is "javax_imageio_1.0". For coverage I/O, it could be something like: geotools_imageio_1.0 Not sure if we should insert the "stream" word somewhere or not... Page 19 said: > the “axis” node reports the name of the bands associated to the coverage (for > instance in the above example, Wind Velocity can have the U and V bands). I'm a little bit surprised by the "axis" name, since it could be confused with CRS axis. In my reading of the above sentence, "axis" seems to be used in the sense of "SampleDimension" in OGC 01-004. Is the "axis" name part of some specification for this purpose? A quick search in "GML in JPEG 2000" show me "axisName" used in the usual sense of CRS axis... Page 21, figure 6: bandKeys -------- See previous paragraph. I don't understand why band informations appear as axis properties. I would expect them as coverage-specific information (on "bandKeys" for each coverage), and I would expect them to be named "sampleDimensions" instead. singleValue ----------- Do we really need a "singleValue" element for each vertical position? IIOMetadataFormat cleary allows storage of arrays. See for example: http://java.sun.com/javase/6/docs/api/javax/imageio/metadata/IIOMetadataFormatImpl.html#addAttribute(java.lang.String,%20java.lang.String,%20int,%20boolean,%20int,%20int) Then, why not store the vertical values straight into <values> (child of <VerticalExtent>) as a space-separated list? Same remarks applies to <timePosition>. min,max,res ----------- Could we use full names instead? ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
