Extended pCOS paths. The pCOS (PDFlib Comprehensive Object Syntax) interface provides a simple and elegant facility for retrieving arbitrary information from all sections of a PDF document which do not describe page contents, such as page dimensions, metadata, interactive elements, etc. Examples for using the pCOS interface and a description of the pCOS path syntax are contained in the pCOS Path Reference which is available as a separate document. Additional examples can be found in the pCOS Cookbook at www.pdflib.com/pcos-cookbook/. pCOS can be used in TET PDF IFilter to address information about a document. pCOS paths represent some aspect of the PDF document such as bookmarks, font name, or page size, and can also address document info entries or XMP metadata streams (but not properties within an XMP stream). While the pCOS API functions are not available in TET PDF IFilter, you can supply pCOS paths as expressions in the XML configuration file in order to index information about a document Table 3.1 lists the pCOS paths for some commonly used PDF objects. Many pCOS objects are represented by arrays which require an array index in angle brackets, e.g. pages[0] denotes the first page (pages are counted starting at 0). In addition to all pCOS paths supported by the TET product (which forms the basis of TET PDF IFilter), the IFilter supports the following syntax extension for pCOS paths: You can use a » * « (asterisk) wildcard character instead of an array or dictionary index. This means that TET PDF IFilter will iterate over all possible values of the array index, and include all corresponding object values in the indexing process. An arbitrary number of wildcards may be used within a single pCOS path.

XML configuration for metadata sources. Sources of metadata properties can be configured in the Source element (child of the Property element) of the XML configuration file. While the pdfObject attribute contains an extended pCOS path for a PDF object, the xmpName attribute contains the schema prefix and name of an XMP property: 3.1 Sources of Metadata in PDF 39
