All rights reserved. *   *    The Harvest software was developed by the Internet Research Task *    Force Research Group on Resource Discovery (IRTF-RD): *   *          Mic Bowman of Transarc Corporation. *          Peter Danzig of the University of Southern California. *          Darren R.

Users should consult the individual *    copyright notices in the ``components/'' subdirectories for *    copyright information about other software bundled with the *    Harvest source code distribution. *   *  TERMS OF USE *     *    The Harvest software may be used and re-distributed without *    charge, provided that the software origin and research team are *    cited in any use of the system.  Most commonly this is *    accomplished by including a link to the Harvest Home Page *    (http://harvest.cs.colorado.edu/) from the query page of any *    Broker you deploy, as well as in the query result pages.  These *    links are generated automatically by the standard Broker *    software distribution. *     *    The Harvest software is provided ``as is'', without express or *    implied warranty, and with no support nor obligation to assist *    in its use, correction, modification or enhancement.  We assume *    no liability with respect to the infringement of copyrights, *    trade secrets, or any patents, and are not responsible for *    consequential damages.  Proper use of the Harvest software is *    entirely the responsibility of the user. *   *  DERIVATIVE WORKS *   *    Users may make derivative works from the Harvest software, subject  *    to the following constraints: *   *      - You must include the above copyright notice and these  *        accompanying paragraphs in all forms of derivative works,  *        and any documentation and other materials related to such  *        distribution and use acknowledge that the software was  *        developed at the above institutions. *   *      - You must notify IRTF-RD regarding your distribution of  *        the derivative work. *   *      - You must clearly notify users that your are distributing  *        a modified version and not the original Harvest software. *   *      - Any derivative product is also subject to these copyright  *        and use restrictions. *   *    Note that the Harvest software is NOT in the public domain.  We *    retain copyright, as specified above. *   *  HISTORY OF FREE SOFTWARE STATUS *   *    Originally we required sites to license the software in cases *    where they were going to build commercial products/services *    around Harvest.  In June 1995 we changed this policy.  We now *    allow people to use the core Harvest software (the code found in *    the Harvest ``src/'' directory) for free.  We made this change *    in the interest of encouraging the widest possible deployment of *    the technology.  The Harvest software is really a reference *    implementation of a set of protocols and formats, some of which *    we intend to standardize.  We encourage commercial *    re-implementations of code complying to this set of standards.   *   */#ifndef _RECOGNIZE_H_#define _RECOGNIZE_H_#ifndef _PARAMS#if defined(__STDC__) || defined(__cplusplus) || defined(__STRICT_ANSI__)#define _PARAMS(ARGS) ARGS#else /* Traditional C */     #define _PARAMS(ARGS) ()      #endif /* __STDC__ */              #endif /* _PARAMS */   int init_type_recognize _PARAMS((char *, char *, char *, char *));int type_recognize _PARAMS((DataObject *));int type_recognize_by_name _PARAMS((DataObject *));int type_recognize_by_content _PARAMS((DataObject *));int type_recognize_by_stat _PARAMS((DataObject *));int type_recognize_by_url _PARAMS((DataObject *));int type_recognize_by_external _PARAMS((DataObject *));void finish_type_recognize _PARAMS(());#endif /* _RECOGNIZE_H_ */
