Metacat is a flexible database storage system for XML formatted
41 2313 jones
documents and associated binary files. Metacat models the structure of the
42
XML document, therefore allowing storage of XML documents with arbitrary
43
schemas. Metacat supports several databases on the back-end, including Oracle,
44
PostgreSQL and SQL Server (limited).  The server supports XML document
45 2441 jones
storage, retrieval, query, validation, and transformation (using the XSLT
46 2313 jones
stylesheet language).  In addition, there is a mechanism for replicating the
47
database to other metacat instances for backup and load balancing purposes.
48
Metacat currently uses an LDAP database for authenticating users, but was
49
written to accomodate other authentication services as well.

Release Notes for 1.9.1:
89
------------------------
90
The 1.9.1 release holds the bug fixes found after releasing 1.9.0 beta.
91
These bugs were primarily replication issues.  There is no difference
92
in functionality between 1.9.0 and 1.9.1

Release Notes for 1.9.0:
95
------------------------
96
This release focuses on simplifying the Metacat installation process by
97
creating a binary (war) installation.  The need to build the application
98
on the server has been removed (although the option is still available).
99
In order to facilitate this method of installation, a few major modifications
100
were made to the code:
101
102
  -- Ant token replacement was removed for all non-build variables in the
103
     application (most of this was already done in 1.8.1).
104
105
  -- The Metacat properties confguration was moved into the application
106
     itself.
107
108
  -- Database schema version detection and install/upgrade utilities were
109
     added to the application.
110
111
Also, this release includes several enhancements:
112
  -- it supports the new EML 2.1.0 version.
113
114
  -- Documents are now stored on the local filesystem as well as in the
115
     database in order to preserve document integrity.
116
117
  -- Metacat verifies new schemas when they are added.
118
119
  -- Additional access is propegated with documents during replication.
120
121
High priority bugs were addressed in this release as well.
122
123
The enhancements/bugs addressed are:
124
125
* escaped "less than" in inlinedata causes invalid eml output (Bug 2564)
126
* need to set filename for download files (Bug 2566)

Release Notes for 1.8.1:
156
------------------------
157 3934 tao
This release focuses on bug fixes. In this release, the problem that Metacat 1.8.0 and previous
158 3925 tao
versions use illegitimate EML 2.0.1 schemas is addressed: first, Metacat 1.8.1 comes with
159
legitimate EML 2.0.1 schemas; second, existing invalid EML 2.0.1 documents will be
160 3930 tao
automatically fixed while maintaining their package ID during the Metacat 1.8.1 upgrading process.
161 3925 tao
Details please see:
162
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=3239
163
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=3241
164
165 3955 tao
Note: after upgrading the Metacat to version 1.8.1, some replication issues may be seen, e.g., the
166
EML 2.0.1 documents from Metacat 1.8.0 or ealier verions may be rejected since Metacat 1.8.1 uses
167
different EML 2.0.1 schemas (see bug 3239). If this is case, Metacat administrators should notify
168
their counterparts to upgrade previous version Metacats to 1.8.1.
169
170 3925 tao
The fixed bugs include:
171
172
*Character set (charset) problem when filling out form (Bug2797)
173
*Charset bug: > "less than" symbol does not display correctly (Bug2517)
174
*Metacat performance issue in Sanparks skin (Bug 3174)
175
*Metacat using illegitimate versions of EML schema (Bug 3239)
176
*Update older invalidated eml201 document in Metacat (Bug 3241)
177
*Verify existing token changes to skins (Bug 3176)
178
*The edit feature in the NCEAS Data Repoistory does not work (Bug 2644)
179
*Expose permission options for registry uploads (Bug 3014)
180
*ESA registry doesn't have LTER in login dropdown menu (Bug 2647)
181
*Data Catalog Map is slow when selecting (Bug2732)
182

235 3020 sgarg
236 3109 perry
New Features:
237
* Three new open source libraries have been integrated with Metacat:
238
  - Geoserver:  A standards-compliant web map server to publish
239
                geographic data to the web.

Release Notes for 1.6.0:
266
------------------------
267
268
This release comes with more performance improvements, initial support for
269
LSIDs (Life Sciences Identifiers) and FGDC standard, more controls for
270
Metacat administrators and bug fixes. Below is the list of bug fixes and
271
performance improvements.
272
273
Bug Fixes:
274
* Improved the indexing algorithm. Earlier indexing failed for some documents
275
  randomly and used to take a lot of time to complete for others. The
276
  code for indexing was changed to take care of both these problems.
277
* Earlier, xmlns prefix was used to determine the namespace of the document.
278
  Now schemaLocation is used instead xmlns prefix to determine the namespace
279
  of the document as that is a better indicator of document type.
280
* INSTR was used in some SQL statements and it is not supported by Postgres.
281
  So SQL statements were modified so that INSTR is not used.
282 3025 sgarg
* Replication was changed to include replication of deleted documents also.
283
* Fixed bug in squery which didnt allow use of not-contains
284 3020 sgarg
285
New Features:
286
* Added FGDC schema and XSLT so that Metacat can handle FGDC standard
287
* Added support for LSID. This includes modifying the stylesheets to
288
  display the LSIDs, modifying the build to include a new target
289
  'install-ldap'.
290
* Added following access control levels to Metacat:
291
    1. Administrators - users who can do the following:
292
       a. Run replication
293
       b. Delete any document
294
       c. Modify any document
295
       d. run indexing for any document
296
       e. check the logs
297
    2. allowedUsers - User who are allowed to submit
298
    3. deniedUsers - Users not allowed to submit
299
* Added a new skin for Ecological Society of America.
300 3025 sgarg
* Created an Advanced search servlet which can be used from the web.
301
* Various connections have been modified to be secure. e.g. connection between
302
ldaps is made secure now, replication is done over secure channels.
303 3020 sgarg
304
Performance:
305
* Reduced size of xml_nodes by creating a new table for holding nodes from
306
  deleted documents and old revisions of the documents.
307
* Provided a new variable in metacat.properties where more frequently searched
308
  for paths can be specified. Seperate indexes are created for these paths
309
  - so that search is faster.
310 3025 sgarg
* Included log4j for logging and debuging to prevent wasting of time in printing log statements.
311 3020 sgarg
312 2475 sgarg
Release Notes for 1.5.0:
313
------------------------
314
315 2479 jones
This release comes with performace improvement, user interface enhancements,
316 2475 sgarg
and bug fixes. Below is the list of bug fixes and performance improvements.
317
318
Bug Fixes:
319
* Modify property values of harvester registration servlets to match the
320
  servlet-mapping URL values in web.xml. The old values used the servlet
321
  class names. This worked in Tomcat 4 but seems to break in Tomcat 5 on
322
  Windows. The new values use the servlet-mapping URL values. This should
323
  work in both Tomcat 4 and Tomcat 5. (Bug 162)
324
* Re-implement logic to prune old log entries from the HARVEST_LOG and
325
  HARVEST_DETAIL_LOG tables. The old logic caused integrity constraint
326
  violations in the database because it tried to delete parent records from
327
  HARVEST_LOG prior to deleting child records from
328
  HARVEST_DETAIL_LOG. (Bug 162)
329
* In data registry, minor bugs fixed like the error page shows the link back
330
  to the form when error page was generated because of a document read
331
  request from search results page,  the successful delete button leading
332
  to a blank screen and the old ACL overwritten by the registry.
333
  (Bugs 1307, 1310, 1322, 1344, 1551)
334
* Changed the code to support insertion of following characters: ', `,
335
  charcters in the Numeric Character Reference format (&#xyz;) and
336
  characters like µ. Characters like µ will be converted to and stored in
337
  Numeric Character Reference format(&#xyz;). They will also be returned
338
  in Numeric Character Reference and it is upto the client to convert them
339
  and display them accordingly in the application. Partial fix provided by
340
  Johnoel Ancheta. (Bug 1538,1711)
341
* Spatial search failed on Oracle because of invalid entries made by
342
  some documents in the nodedata column of xml_nodes for paths involving
343
  'eastBoundingCoordinate', 'westBoundingCoordinate',
344
  'northBoundingCoordinate', 'southBoundingCoordinate'. A new column
345
  nodedatanumerical was added to xml_nodes table such that all the numerical
346
  nodedata is stored in this column and this column is now used for spatial
347
  search. (Bug 1703, 1718)
348
* In the default skin, clicking on the keywords on the home page did not
349
  result is a search being done. Fix provided by Owen Jones. (Bug 1768)
350
* Metacat generated a success message even when a document which didnt
351
  exsist was requested for deletion. This has been fixed. (Bug 1850)
352
* "packagetype" in xml-relation table was entered as eml200 namespace when
353
  an eml201 document was inserted. This is fixed now so that "packagetype"
354
  in xml-relation table points to eml201 namespace. (Bug 1979)
355
* System_id in xml_catalog pointed to http://knb.ecoinformatics.org/knb/
356
  earlier. Fixed such that it points to the locally installed metacat url.
357
  (Bug 1986)
358
* Changes to the Query subsystem fix bugs that prevented attributes from
359
  being expressed solely in the xpath query statement and the returnfield
360
  values. For instance, a query URL may now include search strings like
361
  '@packageId=sbclter%25' and return strings like 'returnfield=@packageId'.
362
  Previously, the attribute had to be appended to an element:
363
  '/eml/@packageId=sbclter%25'. These fixes change DBQuery.java,
364
  QuerySpecification.java, and QueryTerm.java (Bug 2052)
365
* Search query failed in case of Oracle if number of documents in the result
366
  were more than 1000. This has been fixed. (Bug 2000)
367
* Removed any occurence of enum which is now a keyword in Java 1.5
368
369
370
Enhancements:
371
* Major improvements done in user interface for the data registeries and
372
  various other skins. Improvements done based on suggestions from Mark
373
  Stromberg, Laura Downey and others. Improvements also done in resultset.xsl,
374
  the default skin and ldap templates. (Bug 1948)
375
* Coded added such that administrator can delete documents irrespective of
376
  who the document belongs to.
377
* Performance impovement done in searching of datasets. A part of the search
378
  time was taken up because of generation of resultset after the search had be
379
  done. So this was the sequence of events in earlier metacat
380
  1) Search for the given text
381
  2) A list of docids generated
382
  3) For each of the docids
383
     3a) Use xml_index and xml_nodes table to generate the string descibing
384
         the document including the returnfields requested in the search
385 2479 jones
  4) Add all the strings from step 3a to send back the resultant
386
     document. Here a decent amount of time was being taken by step 3a.
387
  The algorithm is now modified by addition of two tables xml_queryresult and
388
  xml_returnfields and a user defined parameter xml_returnfield_count. The
389
  new algorithm works as follows:
390 2475 sgarg
  1) Search for the given text
391 2479 jones
  2) A list of docids is generated
392 2475 sgarg
  3) For the given set of return fields generate a unique string and check
393
     if that string exists in xml_returnfields
394
     3a) If string does not exist in xml_returnfield, then enter a new
395
         record usage_count as 1 and returnfield_string as the unique string
396
         generated above.
397
     3b) Else if the string exists, increment usage_count
398
  4) Given the docids from step 2 and the id of the returnfield record from
399
     step 3, query for any docids that already exist in xml_queryresult.
400
     For the docids that do exist, get the queryresult_string.
401
  5) For rest of the docids from step2 which were not found in step 4, do
402
     the following for each of the documents:
403
     5a) Use xml_index and xml_nodes table to generate the string descibing
404
         the document including the returnfields requested in the search
405
     5b) If usage_count of the record from step is more than
406
         xml_returnfield_count set in metacat.properties, then store the
407
         string in xml_queryresult as a record which has the returnfield_id
408
         representing the set of returnfields, docid representing the
409
         document and the string as queryresult_string.
410
  6) Add all the strings from step 4 and step 5a to send back the resultant
411
     document
412
  So the results from step 3a in previous algorithm are effectively cached
413
  and hence same computation is not done again and again for each search.
414
  When a document is deleted, all the entries for that document in
415
  xml_queryresult table are also deleted. When a document is updated, all
416
  the entries for that document in xml_queryresult table are deleted. This
417
  works fine because those entries will be generated and cached again the
418
  next time the document is part of a search is requested.
419
* Performance impovement done for % search.
420
* Following new functions added to metacat client API: a method to set access
421
  on an xml document and a method to get newest version for a given document.
422
* Implement a new HarvesterServlet for running Harvester as a servlet. This
423
  eliminates the need to run Harvester in a terminal window. By default, the
424
  HarvesterServlet is commented out in lib/web.xml.tomcat(3,4,5). The user
425
  documentation will be modified to instruct Harvester administrators to
426
  uncomment the HarvesterServlet entry.
427
* Minor enhancement to support multiple email addresses for harvester
428
  administrator and site contact. Each address is separated by a comma or
429
  semicolon.
430
* Increase number of rows in Harvest List Editor from 300 to 1200.
431
* Changed default maxHarvests value to 0. Added logic to ignore maxHarvests
432
  value when it is set to 0 or a negative number. This allows Harvester to
433
  run indefinitely without shutting down after reaching a maximum number of
434
  harvests. The previous default value of 30 would cause Harvester to
435
  terminate after 30 harvests.

Release Notes for 1.4.0:
442
------------------------
443
444
This is a major release, and is the first to introduce many new features to
445
Metacat.  Some of the major new features in this version of Metacat include:
446
447
* Added a new 'Harvester' that allows documents to be periodically pulled
448
  from distributed sources into metacat, useful for interfacing with other
449
  system types. See the Metacat Tour for details.
450
* Added new 'skins' capability to allow the GUI for the metacat web interface
451
  to be more easily customized to fit into site needs.  The skin is based on
452
  a flexible mix of XSLT, CSS, and Javascript.
453 2321 jones
* Added a web-based metadata entry form for submitting limited EML documents
454 2313 jones
  as part of a data registry.  The GUI for the registry is customizable and
455
  is integrated with the 'skins' system for the main metacat interface.  The
456
  registry subsystem is written in Perl, and can simultaneously be used to
457
  present multiple 'registry' interfaces.
458
* A new 'client API' has been developed and implemented in Java and in Perl
459
  so that metacat functions can be accessed from any program in those
460
  languages.  The client API supports the major metacat servlet actions,
461
  including login(), logout(), query(), insert(), update(), delete(), and
462
  upload(). See the Metacat Tour for details.
463
* Added a new 'getlog' action that produces a usage history for all major
464
  events.  So now an XML report can be generated for document reads, inserts,
465
  deletes, etc.  See the new section in the Metacat Tour.
466
* Added a new 'buildindex' action that can rebuild the index entries for any
467
  document in the database.
468
* The configuration file for metacat (metacat.properties) has been moved out
469
  of the jar file and into the WEB-INF directory, allowing far easier changes
470
  to the configuration parameters.
471 2321 jones
* Results in default web interface are sorted by title in the XSLT
472
  (configurable)
473
* Many bugs were fixed.

Release Notes for 1.3.1:
479 2313 jones
------------------------
480 1308 tao
481 1775 tao
This is a simple interim bug fix. No major functionality changes. Bugs fixed
482
include:
483 1776 tao
 1) Metacat 1.3.0 doesn't work in Java 1.3 because a subtle API differnce in
484
    Java 1.3 and Java 1.4. Currently, Metacat 1.3.1 will work in both Java 1.3
485
    and Java 1.4.
486 1775 tao
 2) Distribution package size was reduced.
487
488
489
Release Notes for 1.3.0
490 2313 jones
------------------------
491 1775 tao
492
In 1.3.0 release, the structure of the xml_access table was changed and a new
493 1628 tao
table, xml_accesssubtree was added. If you try to update a previously
494
installed Metacat, you should run a script file to updated the table structure
495
before installation.
496
For Oracle user: At the SQLPLUS prompt type the following -
497
@src/reviseformetacat13.sql
498
For Postgresql user: At install directory prompt type the following -
499
psql exp < src/reviseformetacat13_postgres.sql
500
(where 'exp' is the database name).
501 1334 tao
502 1628 tao
After installation, user should run "ant schemasql" command to register EML2
503
schema in xml_catalog table.
504
505
If you are a new Metacat user, this step is unneeded.
506
507 1769 tao
Note: 1) We recommend to use Tomcat 4 and JAVA 1.4 to run Metacat. Otherwise,
508
         it will cause potential replication issues.
509
      2) Delete the xercesImpl.jar and xmlParserAPIs.jar files
510
         which are in $CATALINA_HOME/common/endorsed. They are old version and
511
         don't support XML schema validation.
512
513 1628 tao
New Features in 1.3.0
514
  1) Partialy support EML2 document. User can store, query, read and write
515
     EML2 documents. However, Metacat only support access control in resource
516
     level. The subtree level access control will be ignored.
517
  2) Support other xml document base on namespace/schema.
518
  3) Support query for attribute value
519
  4) Assign MIME type to data file base on metadata when user try to read it.
520
  5) Owner can assign access rules to a document which does not have access
521
     document to apply it.
522
  6) Support exporting single file, not only whole package
523 1769 tao
  7) Resupport Microsoft SQL Server.
524 1628 tao
525
Fixes in 1.3.0:
526
  1) Couldn't finish delta T replication for large set of documents.
527
  2) Couldn't create access control during delta T replication.
528
  3) Eorr will be written to a seperated log file if some documents
529
     were failed in replication.
530
  4) Decrease the time to create access rules during insert or update
531
     a package.
