No filter must be specified explicitely for metadata objects. Metadata must be embedded in clear text so non-PDF-aware applications can extract the XMP metadata.(c) ISO 19005-1:2005

How to remove the filter in the metadata of a PDF? AcrobatPro v.10.

In "Internal PDF structure" there is a string: "Filter: FlateDecode". If I understand correctly, the problem in compression.

But remove the compression settings in "Optimize PDF" does not solve the problem.

This is specifically for PDF/A compliant files, and does not apply to normal PDF documents. When you convert your document to a PDF/A file, then the metadata should be saved correctly. Other than that, I am not aware of another way to force the metadata dictionary to be saved uncompressed from within Acrobat. [ Update: It can actually be done using the PDF Optimizer, see further down for more information ]

Are you running into problems with PDF/A files and compressed metadata dictionaries?

Yes, I need create a correct PDF/A file, but when I save the filters remain in the metadata.

How exactly are you creating PDF/A files? Which PDF/A "flavor" are you using? I just did a quick test, and when I use the PDF/A profiles in Preflight, a compressed metadata stream is correctly uncompressed and saved in the resulting PDF/A file.
