    摘要: Described is the adding of padding to a content file (e.g., image and/or audiovisual file) for anticipated subsequent use such that the content file need not be re-encoded to add metadata and other data to it. For example, padding may be added to an image file directly after an image file directory, whereby the directory can grow as needed into the padded space. Metadata can likewise be added to the padding, e.g., from the opposite direction that the directory extends into the padding. The padding may be added on the first re-encoding of the file, reducing or eliminating the need for subsequent re-encoding. The padding also may be used to track dead space in the file, with adjacent regions of dead space coalesced into a single region of dead space.

    摘要: An improved system and method for an extensible metadata architecture for digital images is provided. Executable software code may be operably coupled to a metadata query reader and a metadata query writer for requesting operations for manipulating metadata in an image file. The metadata query reader may be operably coupled to a decoder having a block reader for identifying metadata blocks in an image file and associating a metadata reader with each metadata block. Each metadata reader may then enumerate the metadata in the metadata block associated with that metadata reader. The metadata query writer may be operably coupled to an encoder having a block writer for associating a metadata writer with each metadata block to be written to an image file. Each metadata writer may then write metadata in the metadata block associated with that metadata writer.
