B Oracle Text Supported Document Formats

This appendix contains a list of the document formats supported by the automatic (AUTO_FILTER) filtering technology. The following topics are covered in this appendix:

B.1 About Document Filtering Technology

The automatic filtering technology in Oracle Text uses Oracle Outside in HTML Export technology. This technology also enables you to convert documents to HTML for document presentation with the CTX_DOC package.

To use automatic filtering for indexing and DML processing, you must specify the AUTO_FILTER object in your filter preference.

To use automatic filtering technology for converting documents to HTML with the CTX_DOC package, you need not use the AUTO_FILTER indexing preference, but you must still set up your environment to use this filtering technology, as described in this appendix.

Note:

The underlying technology used by Oracle Text was migrated to Oracle Outside in HTML Export in release 11.1.0.7. See "Formats No Longer Supported in 11.1.0.7" for a list of formats that are no longer supported as a result of this migration. Applications that require support for those formats can use USER_FILTER to plug in third-party filtering technology supporting those formats. See "USER_FILTER" for more information.

B.1.1 Latest Updates for Patch Releases

The supported platforms and formats listed in this appendix apply for this release. These supported formats are updated for patch releases.

B.1.2 Restrictions on Format Support

Password-protected documents and documents with password-protected content are not supported by the AUTO_FILTER filter.

For other limitations, refer to sections in this chapter concerning specific document types.

B.1.3 Supported Platforms for AUTO_FILTER Document Filtering Technology

Several platforms can take advantage of AUTO_FILTER filter technology.

B.1.5 PDF Filtering Limitations

The following limitations apply when filtering PDF files:

  • Multi-byte PDFs are supported, provided the PDF document is created using Character ID-keyed (CID) fonts, predefined CJK CMap files, or ToUnicode font encodings, and the document does not contain embedded fonts.

  • Embedded fonts in a PDF document are not filtered correctly. They are usually displayed using the question mark (?) replacement character.

  • Hyperlinks in a PDF are not active when displayed in a browser or a viewing window.

  • Annotations, such as notes, sound, or movies, are not supported.

B.1.6 Environment Variables

No environment variables need to be set by the user.

B.1.7 General Limitations

AUTO_FILTER filter technology has the following limitations:

  • Any ASCII characters less then 0x20 (decimal 32) are converted to hexadecimal numbers.

  • Files larger than 2GB are not handled.

B.2 Supported Document Formats

The tables in this section list the document formats that Oracle Text supports for filtering.

Document filtering is used for indexing, DML, and for converting documents to HTML with the CTX_DOC package.

Note:

These lists do not represent the complete list of formats that Oracle Text is able to process. The USER_FILTER and PROCEDURE_FILTER enable Oracle Text to process any document format, provided an external filter exists that can filter to some textual format like plain-text, HTML, XML, and so forth.

B.2.9 Formats No Longer Supported in 11.1.0.7

Certain document formats are not supported if you upgrade from release 11.1.0.6 to 11.1.0.7. This is because Oracle Text filtering technology has been migrated to Oracle Outside in HTML Export technology. To filter these unsupported formats, you can plug in a third party filtering technology using USER_FILTER. See "USER_FILTER" for more information.

Table B-4 lists the formats supported in release 11.1.0.6, but not in 11.1.0.7.
