This appendix contains a list of the external filter formats supported for use in mixed-format columns. It also provides details for installation, setup, and usage of the external filters provided by ConText.
The following topics are covered in this appendix:
For more information about external filters, see "External Filters" in Chapter 8, "ConText Indexing".
See Also:
The following table lists all of the document formats that ConText supports for columns that use external filters and store documents in more than one format.
For each format, the format ID is also listed. This is the value that must be specified when creating a Filter preference using the BLASTER FILTER Tile with the executable attribute.
|
Note: This list does not represent the complete list of formats that ConText is able to process. The external filter framework enables ConText to process any document format, provided the documents are stored in a single format and an external filter exists which can filter the format to plain text. It also does not represent the list of formats for which Oracle provides external filters. For the complete list of external filters supplied by Oracle, see "Supplied External Filters" in this chapter. |

ConText supplies a set of ready-to-use external filters, licensed from MasterSoft (Inso Corporation), which can be used for filtering documents in many of the most popular desktop publishing and word processor formats.
Because the external filters are supplied as executables, the availability of the filters is platform-dependent; however, the filters are generally supplied for the following platforms/operating systems:
The following filters are supplied by ConText. The executables for the filters do not provide ConText with the required arguments, so ConText also provides scripts which act as wrappers for the executables:
The supplied external filter executables and their wrappers are installed automatically during installation of ConText. The location and format of the executable and wrapper files are operating system dependent.
The supplied external filters do not require any setup, aside from creating preferences that call the wrappers for the filters; however, if you have upgraded from ConText release 2.0 and already have wrappers for the external filters provided in the previous release, as well as preferences that call the wrappers, choose one of the following actions:
Otherwise, you must drop your indexes, policies, and preferences, then create new preferences, policies, and indexes that use the new wrappers/filters.
The supplied external filters have the following usage issues:
You generally do not need to know the name of the filter executables; however, if you find it necessary to modify the wrappers, it may be useful to know the names of the filter executables.
If your operating system requires specifying the complete name of a script in order to run the script, you must include any suffixes in the Filter preferences that you create using the supplied external filters.
