Dear fellow Ptolemy Hackers,
I've created two facilities that I've wanted for some time. First, you can now export a Ptolemy model to a web page. See for example: http://ptolemy.org/~eal/tmp/MaximumEntropySpectrum/ Try clicking on the icons in this model. The above export is what you get by default from a model, but the export can be highly customized. For a customized example, see: http://ptolemy.org/~eal/tmp/EECScourses/ Try clicking on the icons here (the result of a query to a Berkeley campus database is displayed). The web export mechanism is documented in a draft chapter here: http://ptolemy.org/publications/papers/12/PtolemyII_Digital_ExportAppendix.pdf I'm hoping we can use this to provide an easy way to disseminate models to people who don't want to install any software. If you have an up-to-date SVN tree, you can use this immediately. Please send me comments, typos, and suggestions. The second facility is the ability to create a hyperlink in Ptolemy II model. The LiveLink attribute, found in Vergil in the Utilities->Parameters library, can be used to put an annotation into a model that has a hyperlink to another model. Double-clicking on the annotation will take you to the other model. An example is this demo: $PTII/ptolemy/domains/sdf/demo/Spectrum/Spectrum.xml which now has an annotation saying: "See also MaximumEntropySpectrum." Double-clicking on that annotation opens the other model. The documentation for LiveLink reads: An attribute that provides a link to a specified URL. This can be contained by any Ptolemy II object, and when a user double clicks on that object, the result is to open the specified URL. To set the URL, you either Alt-click on the object or right click and select Configure. <p> A common way to use this attribute is to put a text annotation in a model with text something like "See also Foo", where "Foo" is the name of another related model. Drag an instance of this LiveLink attribute onto the text annotation, and double click on the text annotation to set the file name for the model Foo. The file name can be relative to the location of the model containing the annotation. It can also have any of the forms supported by {@link FileParameter}. For example, a file name can begin with $PTII, indicating that the file is in the Ptolemy II installation tree. <p> The default URL is "http://ptolemy.org#in_browser";, which is the home page of the Ptolemy Project with an additional annotation indicating that the page should be opened in a browser. The suffix "#in_browser" will always be interepreted this way. Without this suffix, Vergil will be used to open the URL. Note that Vergil's HTML viewer does not handle many modern pages well. Again, comments and suggestions are welcome. Edward
