B Oracle Text Supported Document Formats

Oracle Text uses the HTML export technology of Oracle Outside In for automatic filtering. This appendix provides tables with the document and graphic file formats supported by the automatic AUTO_FILTER filtering technology for this release.

This appendix contains the following topics:

See Also:

"AUTO_FILTER" for information on using AUTO_FILTER

B.1 About Document Filtering Technology

The automatic filtering technology in Oracle Text 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.

This section contains these topics:

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

The formats listed in this appendix are those formats recognized by AUTO_FILTER. Recognizing a format does not necessarily mean that text can be extracted from it. For example, a scanned document is usually an image and AUTO_FILTER does not perform optical character recognition. Similarly, text cannot be extracted for indexing from multimedia file types.

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

For other limitations, see "Supported Document Formats" concerning specific document types.

B.1.3 Supported Platforms for AUTO_FILTER Document Filtering 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

Document filtering is used for indexing, DML, and for converting documents to HTML with the CTX_DOC package. The tables in this section list the document formats that Oracle Text supports for filtering.

This section contains the following topics:

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.2.1 Archive File Format

When filtering an archive file, all the contents of the files inside the archive will be exported to a single output file. This will also include the contents of all subfolders and files inside the archive file.

Table B-2 lists the archive formats that Oracle Text supports.
