metadata

Where does the convention of using private metadata variables like __author__ within a module come from? This Python mailinglist thread seems to hint at some discussion about it in 2001, but by the sound of it the convention was already out in the wild. Other than that, I can only find this PEP on package metadata , which seems influential but tangental at best. I'd like to try and find some explicit material on the subject so my documentation tool can parse these metadata variables successfully. My guess is, it's from the old times when packaging meta data was not common then. In PEP 8 one is

I'm interested in subclassing django's ImageFileField to allow access to the image IPTC metadata, something like: >>> from myapp.models import SomeModel >>> obj = SomeModel.objects.all()[0] # or what have you >>> obj.image.iptc['keywords'] ('keyword','anotherkeyword','etc') ... the docs say to read over django's internal code , which I did; I've tried to produce a working implementation and I am not sure what I'm doing -- I've defined custom fields before, but I can't come up with boilerplate setup for a file-based field. I know I need to define an attr_class and a descriptor_class to make it

I'm looking into using the html5 data- attributes to pass the validation rules to jquery.validate as a stop gap until the plugin is updated with HTML5 support. I'm using jquery 1.4.2, jquery.validate 1.7 and jquery.validate 2.1. In my HTML I'm using code such as this: <input name="foo" type="text" data-validate="{required:true,digits:true}" /> In my jQuery I'm doing the following: <script type="text/javascript"> $.metadata.setType ("html5"); $(function () { $('#myForm').validate ({debug:true}); }); </script> This just causes an error message, validator.methods[method] is undefined I did do a

I don't understand MEF very well, so hopefully this is a simple fix of how I think it works. I'm trying to use MEF to get some information about a class and how it should be used. I'm using the Metadata options to try to achieve this. My interfaces and attribute looks like this: public interface IMyInterface { } public interface IMyInterfaceInfo { Type SomeProperty1 { get; } double SomeProperty2 { get; } string SomeProperty3 { get; } } [MetadataAttribute] [AttributeUsage(AttributeTargets.Class, AllowMultiple = true)] public class ExportMyInterfaceAttribute : ExportAttribute, IMyInterfaceInfo {

I am writing a Python script to index a large set of Windows installers into a DB. I would like top know how to read the metadata information (Company, Product Name, Version, etc) from EXE, MSI and ZIP files using Python running on Linux. Software I am using Python 2.6.5 on Ubuntu 10.04 64-bit with Django 1.2.1. Found so far: Windows command line utilities that can extract EXE metadata (like filever from SysUtils), or other individual CL utils that only work in Windows. I've tried running these through Wine but they have problems and it hasn't been worth the work to go and find the libs and

Is there a good way to tell who created a stored procedure in SQL Server 2005 (that also works in 2008)? In SQL Management Studio I can right mouse/properties on a proc to get the created date/time but how do I discover the creator? It may be too late for you now, but you can keep track of DDL activity. We have a table in our administrative database that gets all the activity put in it. It uses a DDL trigger, new to 2005. These scripts create a table in your admin DB (SQL_DBA for me), create a trigger on the model db, create triggers on existing databases. I also created a sp_msforeachDB

Java has annotations and that is good. However, some developers feel that it is best to annotate code with metadata using xml files - others prefer annotations but would use metadata to override annotations in source code. I am writing a Java framework that uses annotations. The question is: is there a standard way to define and parse metadata from xml files. I think this is something every framework that uses annotations could benefit from but I can seem to find something like this on the Internet. Must I roll my own xml parsing/validation or has someone already done something like this?
