Add XML namespace in XMP metadata of EPS |Python

To add an XML namespace to the XMP metadata of an EPS file, you need to perform the following steps:

Initialize an input stream for the input EPS file.
Create an instance of PsDocument from the previously created input stream.
Get an instance of XmpMetadata from the PsDocument. If the EPS file does not contain XMP metadata, a new one will be created and populated with values from PS metadata comments, then returned to you.
Now you can add a new XML namespace to the metadata.
Initialize an output stream for the output EPS file.
Save the EPS file with the updated XMP metadata.

The following code example demonstrates how to add an XML namespace to the XMP metadata in an EPS file using Python:

 1# The path to the documents directory.
 2data_dir = Util.get_data_dir_working_with_xmp_metadata_in_eps()
 3# Initialize an EPS file input stream
 4ps_stream = open(data_dir + "add_simple_props_input.eps", "rb",)
 5# Create a PsDocument instance from stream
 6document = PsDocument(ps_stream)

 8try:
 9    # Get XMP metadata. If EPS file doesn't contain any XMP metadata we get a new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
10    xmp = document.get_xmp_metadata()
11    
12    #Change XMP metadata values
13    
14    # Add a new XML namespace "tmp".
15    xmp.register_namespace_uri("tmp", "http://www.some.org/schema/tmp#")
16    
17    # Add a new string property in new namespace.
18    xmp.add("tmp:newKey", XmpValue("NewValue"))
19    
20    # Save the EPS file with the changed XMP metadata
21    
22    # Create an ouput stream
23    with open(data_dir + "add_namespace_output.eps", "wb") as out_ps_stream:
24        # Save EPS file
25        document.save(out_ps_stream)
26    
27finally:
28    ps_stream.close()
