+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/River.java:
+	  Added a method maxOverlap to determine the gauge which has
+	  the max common length to a given interval. This is for
+	  numerical stability in slightly overlapping gauge ranges.
+
+2011-06-26	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/model/River.java: When

+
+	* src/main/java/de/intevation/flys/model/River.java:
+	  Added method to find gauge by its name.
+
+2011-06-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/annotation-types.xml: Fixed some rules.
+
+	* src/main/java/de/intevation/flys/importer/Importer.java,
+	  src/main/java/de/intevation/flys/importer/InfoGewParser.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Call the right constructors now.
+
+	* src/main/java/de/intevation/flys/importer/ImportAnnotationType.java:
+	  Added getter/setter for name property.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationsParser.java:
+	  Print duplicated at WARN level not as DEBUG.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationClassifier.java:
+	  Fixed XPath expression to build the internal lookup structures
+	  correctly.
+
+2011-06-19	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Added classification of annotation types. Needs testing!
+
+	* doc/annotation-types.xml: New. Rules to classify the different
+	  types of annotations. The classification works like this:
+
+	  There are unique types like 'Bruecke', 'Pegel' and so on.
+	  They are defined in the /annotation/type section and
+	  identified by their name. One of the types can be set 
+	  as the default type if no rule applies.
+
+	  In the /annotation/pattern section are two types of pattern.
+
+	  1 - file pattern: If a KM file is opened its filename is
+	      matched against the regular expressions of these
+		  patterns. If a match is found the corresponding type
+		  is used as the default type in the open file.
+		  If no match is found the global default type is used
+		  as the default type.
+
+	  2 - line patterns: For each line of an open KM file these
+	      patterns are applied to find a match. If a match is
+		  found the corresponding type is used as the type of
+		  the annotation. If no match is found the default
+		  file default is assumed to be the right type. For
+		  the file default see 1.
+
+	* src/main/java/de/intevation/flys/importer/Importer.java:
+	  To activate the annotation type classification set
+	  the system property
+
+	      'flys.backend.importer.annotation.types'
+
+	  to the path of a XML looking like the annotation-types.xml
+	  file. If the system property is not set no classification
+	  is done.
+
+	* src/main/java/de/intevation/flys/importer/AnnotationClassifier.java:
+	  New. Implements the classification.
+	  
+	* src/main/java/de/intevation/flys/importer/AnnotationsParser.java,
+	  src/main/java/de/intevation/flys/importer/InfoGewParser.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Looped through the annotation type classification.

+
+2011-05-10	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Added a column which tells

+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  Add some unsharp comparison (eps = 1e-6) to avoid 
+	  numerical problems.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Removed. Not need any longer.
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:

+
+	* src/main/java/de/intevation/flys/importer/ImportWst.java,
+	  src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Flush more often. Hopefully this reduces hibernate sync
+	  problems?!
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Fixed silly bug. Set flush mode back to auto because
+	  manual flushing causes some undetermined problems.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Do not load _all_ values from discharge tables and
+	  wst columns. This is extremly slow and will lead
+	  to OOM if more rivers are imported. Now only the
+	  last 20 columns und discharge tables are cached.
+
+	* src/main/java/de/intevation/flys/importer/ValueKey.java:
+	  New. Key for caching discharge table values and wst
+	  column values.
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Fixed bug in equals().
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Removed too eloquent debug output.
+
+2011-05-09	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/IdValueKey.java:
+	  Use BigDecimals as representation for the numeric components
+	  which prevents running into unique constraint problems
+	  caused by imprecision.
+
+	* src/main/java/de/intevation/flys/importer/ImportRange.java,
+	  src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Ranges are now cached globally, too.
+
+	* src/main/java/de/intevation/flys/importer/ImportWstColumn.java:
+	  Improved logging.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
+	  Removed superfluous imports.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/StaFileParser.java:
+	  Only accept main value types 'Q', 'W', 'D' and 'T' by default.
+	  '-' is not handled any more because it causes too much constraint
+	  problems. You can overwrite the imported type with the
+	  system property flys.backend.main.value.types" (default "QWTD")
+	  
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Set session flush mode to manual. Hopefully this improves the
+	  performance a bit.

+	* src/main/java/de/intevation/flys/importer/IdValueKey.java: Reinserted
+	  here in a more generalized form.
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  Cache the discharge table value, too.
+
+	* src/main/java/de/intevation/flys/importer/ImportDischargeTableValue.java:
+	  Use the global cache.
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImporterSession.java:
+	  New. Centralized caching in the thread local context. Importing
+	  the Elbe leads to OOM because the column values of the
+	  WST files where loaded separately for every file.

+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* doc/schema/postgresql.sql: Dropped constraint which
+	  forces discharge tables to have a unique time interval
+	  for a given gauge and kind.
+
+	  There are AT files (historical Mosel/Perl/Perl/1967-1981.at
+	  and Mosel/Perl/1967-1981-1.at) which violate this
+	  constraint. Its a technical question to the customer
+	  how to handle these cases.
+
+	  To adjust existing databases:
+
+	    ALTER TABLE discharge_tables DROP CONSTRAINT discharge_tables_gauge_id_key;
+
+2011-05-08	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/WstParser.java:
+	  There are wst files where column names are not unique.
+	  Make them unique by appending (1), (2) and so on.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	* src/main/java/de/intevation/flys/importer/ImportRiver.java:
+	  Import the "HW-Schutzanlagen", too.
+
+2011-05-05	Sascha L. Teichmann	<sascha.teichmann@intevation.de>
+
+	Make import of historical discharge tables work.
+
+	* doc/schema/postgresql.sql: Added forgotten column 'description'.
+
+	  !!! You have to drop your database !!!

+
+	TODO 1: Speed it up! It takes on a high end machine over 7(!)
+	        minutes only for the data of the Saar.
+	TODO 2: Double precision floating point representations produced
+	        by the the parsers leed to unique constraint violations
+			in the backend on a second run. So the import is currently
+			only working on freshly initialized data bases.
+			More consequent working with BigDecimal and some
+			rounding may be of help here.

+2011-09-19      RELEASE 2.5
+
+    NEW:
+
+        * Improved the data model to support:
+          - cross sections
+          - hyks ("Hydraulische Kenngroessen")
+
+        * Improved the importer to read:
+          - PRF files
+          - HYK files
+
+        * Added a central Config to configure the Importer. There are several
+          system properties to adjust what to import (see ChangeLog for
+          details).
+
+        * Added a Postgis and Oracle models for spatial flys data:
+          - catchments
+          - river axes
+          - buildings
+          - fixpoints
+          - cross section tracks
+          - hws ("HW-Schutzanlagen")
+          - floodplains
+
+        * Bumped Hibernate up to 3.6.5.
+
+        * Bumped Apache DBCP up to 1.4.
+
+
+
+2011-06-27      RELEASE 2.4
+
+    New:
+
+        * Improved the data model to support:
+          - edges ("Oberkante", "Unterkante")
+          - annotations
+
+        * Improved the importer to read:
+          - edges
+          - annotations
+
+        * Made search for gauges in River independent of from/to
+          kilometer order.
+
+
+    Fixes:
+
+        * flys/issue76 Close gaps between q ranges
+
+        * flys/issue110 Fixed import of ATs that skipped the first value.
+
+
+
+2011-05-13      RELEASE 2.3
+
+    New:
+
+        * Import of:
+          - "zusätzliche Längsschnitte"
+          - "Fixierungen"
+          - "amtliche Linien"
+          - "Hochwassermarken"
+          - "Historische Abflusskurven"
+          - "HW-Schutzanlagen"
+
+        * Improvements in the SQL schema:
+          - Added a 'kind' column to WSTs
+          - Added a 'position' column to WST columns to enable sorting WST columns.
+          - Added a 'km_up' column to rivers to determine the flow direction of rivers.
+
+        * Rivers are now able to:
+          - determine their min/max kilometer range
+          - determine the selected gauge(s) based on a kilometer range
+
+        * WSTs are able to determine their min/max Q range.
+
+        * Gauges are able to determine their min/max W range.
+
+        * Added a view 'wst_value_table' that aggregates the data to build w/q
+          value tables.
+
+        * Added one-to-many relation Wst -> WstColumn
+
+        * Speedup of the importer by using an internal caching mechanism.
+
+        * Sta-Parse just accepts the following main value types: 'Q', 'W', 'D' and 'T'
+
+
+    Fixes:
+
+        * Fixed import of Q ranges in wst files.
+
+        * Fixed flys/issue19: Do not take km column in wst file as a water level.
+
+        * Fixed flys/issue11 (Diagramm: Fehlerhafte Werte in Abflusskurven)
+
+        * Fixed flys/issue51 (WINFO: Fachdaten am Pegel Perl enthält Sprünge)
