+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
+<chado table name>.views.inc:
+	contains a single function retrieve_<chado table name>_views_data()
+	which describes that table to views. This function is called by
+	tripal_analysis_views_data() in ../tripal_analysis.views.inc.
+	For more information on the form of this data array look up the
+	views2 documentation for hook_views_data() 
+	-http://views2.logrus.com/doc/html/index.html
+	
+handlers/
+	Each file contained within this folder defines a views handler. Only custom
+	handlers are included in this folder and each must be described in 
+	hook_views_handlers() in ../tripal_analysis.views.inc.
+	A views handler does one of the following:
+		1) describe the type of a field and how it should be displayed
+		2) describe a method to sort this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_analysis.views.inc:tripal_analysis_views_data()
+         by adding the following line:
+            $data = array_merge($data, retrieve_XXX_views_data());
+         to the function and including the file directly above the function (blow the function 
+         header by adding:
+            require_once('views/XXX.views.inc');

+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
+<chado table name>.views.inc:
+	contains a single function retrieve_<chado table name>_views_data()
+	which describes that table to views. This function is called by
+	tripal_core_views_data() in ../tripal_core.views.inc.
+	For more information on the form of this data array look up the
+	views2 documentation for hook_views_data() 
+	-http://views2.logrus.com/doc/html/index.html
+	
+handlers/
+	Each file contained within this folder defines a views handler. Only custom
+	handlers are included in this folder and each must be described in 
+	hook_views_handlers() in ../tripal_core.views.inc.
+	A views handler does one of the following:
+		1) describe the type of a field and how it should be displayed
+		2) describe a method to sort this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_core.views.inc:tripal_core_views_data()
+         by adding the following line:

-File Descriptions:
-========================================================================
+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
 <chado table name>.views.inc:
 	contains a single function retrieve_<chado table name>_views_data()
 	which describes that table to views. This function is called by
-	<tripal module>_views_data() in ../<tripal module>.views.inc.
+	tripal_db_views_data() in ../tripal_db.views.inc.
 	For more information on the form of this data array look up the
 	views2 documentation for hook_views_data() 
 	-http://views2.logrus.com/doc/html/index.html
 	
 handlers/
-	A folder which contains symbolic links to tripal_core/views_handlers/ files.
 	Each file contained within this folder defines a views handler. Only custom
 	handlers are included in this folder and each must be described in 
-	hook_views_handlers() in ../<tripal module>.views.inc.
+	hook_views_handlers() in ../tripal_db.views.inc.
 	A views handler does one of the following:
 		1) describe the type of a field and how it should be displayed
 		2) describe a method to sort this field
-		3) describe a method to filter this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_db.views.inc:tripal_db_views_data()
+         by adding the following line:

-File Descriptions:
-========================================================================
+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
 <chado table name>.views.inc:
 	contains a single function retrieve_<chado table name>_views_data()
 	which describes that table to views. This function is called by
-	<tripal module>_views_data() in ../<tripal module>.views.inc.
+	tripal_feature_views_data() in ../tripal_feature.views.inc.
 	For more information on the form of this data array look up the
 	views2 documentation for hook_views_data() 
 	-http://views2.logrus.com/doc/html/index.html
 	
 handlers/
-	A folder which contains symbolic links to tripal_core/views_handlers/ files.
 	Each file contained within this folder defines a views handler. Only custom
 	handlers are included in this folder and each must be described in 
-	hook_views_handlers() in ../<tripal module>.views.inc.
+	hook_views_handlers() in ../tripal_feature.views.inc.
 	A views handler does one of the following:
 		1) describe the type of a field and how it should be displayed
 		2) describe a method to sort this field
-		3) describe a method to filter this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_feature.views.inc:tripal_feature_views_data()
+         by adding the following line:
+            $data = array_merge($data, retrieve_XXX_views_data());

-File Descriptions:
-========================================================================
+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
 <chado table name>.views.inc:
 	contains a single function retrieve_<chado table name>_views_data()
 	which describes that table to views. This function is called by
-	<tripal module>_views_data() in ../<tripal module>.views.inc.

 	For more information on the form of this data array look up the
 	views2 documentation for hook_views_data() 
 	-http://views2.logrus.com/doc/html/index.html
 	
 handlers/
-	A folder which contains symbolic links to tripal_core/views_handlers/ files.
 	Each file contained within this folder defines a views handler. Only custom
 	handlers are included in this folder and each must be described in 
-	hook_views_handlers() in ../<tripal module>.views.inc.
+	hook_views_handlers() in ../tripal_library.views.inc.
 	A views handler does one of the following:
 		1) describe the type of a field and how it should be displayed
 		2) describe a method to sort this field
-		3) describe a method to filter this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_library.views.inc:tripal_library_views_data()
+         by adding the following line:

-File Descriptions:
-========================================================================
+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
 <chado table name>.views.inc:
 	contains a single function retrieve_<chado table name>_views_data()
 	which describes that table to views. This function is called by
-	<tripal module>_views_data() in ../<tripal module>.views.inc.
+	tripal_organism_views_data() in ../tripal_organism.views.inc.
 	For more information on the form of this data array look up the
 	views2 documentation for hook_views_data() 
 	-http://views2.logrus.com/doc/html/index.html
 	
 handlers/
-	A folder which contains symbolic links to tripal_core/views_handlers/ files.
 	Each file contained within this folder defines a views handler. Only custom
 	handlers are included in this folder and each must be described in 
-	hook_views_handlers() in ../<tripal module>.views.inc.
+	hook_views_handlers() in ../tripal_organism.views.inc.
 	A views handler does one of the following:
 		1) describe the type of a field and how it should be displayed
 		2) describe a method to sort this field
-		3) describe a method to filter this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_organism.views.inc:tripal_organism_views_data()
+         by adding the following line:

+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
+<chado table name>.views.inc:
+	contains a single function retrieve_<chado table name>_views_data()
+	which describes that table to views. This function is called by
+	tripal_phenotype_views_data() in ../tripal_phenotype.views.inc.
+	For more information on the form of this data array look up the
+	views2 documentation for hook_views_data() 
+	-http://views2.logrus.com/doc/html/index.html
+	
+handlers/
+	Each file contained within this folder defines a views handler. Only custom
+	handlers are included in this folder and each must be described in 
+	hook_views_handlers() in ../tripal_phenotype.views.inc.
+	A views handler does one of the following:
+		1) describe the type of a field and how it should be displayed
+		2) describe a method to sort this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_phenotype.views.inc:tripal_phenotype_views_data()
+         by adding the following line:
+            $data = array_merge($data, retrieve_XXX_views_data());
+         to the function and including the file directly above the function (blow the function 
+         header by adding:
+            require_once('views/XXX.views.inc');

+	which describes that table to views. This function is called by
+	tripal_project_views_data() in ../tripal_project.views.inc.
+	For more information on the form of this data array look up the

+	
+handlers/
+	Each file contained within this folder defines a views handler. Only custom
+	handlers are included in this folder and each must be described in 
+	hook_views_handlers() in ../tripal_project.views.inc.
+	A views handler does one of the following:
+		1) describe the type of a field and how it should be displayed
+		2) describe a method to sort this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_project.views.inc:tripal_project_views_data()

+This directory contains all additional views code needed to integrate this module with views2.
+
+FILE/FOLDER DESCRIPTIONS
+---------------------------
+<chado table name>.views.inc:
+	contains a single function retrieve_<chado table name>_views_data()
+	which describes that table to views. This function is called by
+	tripal_pub_views_data() in ../tripal_pub.views.inc.
+	For more information on the form of this data array look up the
+	views2 documentation for hook_views_data() 
+	-http://views2.logrus.com/doc/html/index.html
+	
+handlers/
+	Each file contained within this folder defines a views handler. Only custom
+	handlers are included in this folder and each must be described in 
+	hook_views_handlers() in ../tripal_pub.views.inc.
+	A views handler does one of the following:
+		1) describe the type of a field and how it should be displayed
+		2) describe a method to sort this field
+		3) describe a method to filter this field
+
+
+STANDARDS TO FOLLOW
+---------------------------
+
+1. All table definition files should be named tablename.views.inc
+2. All handlers should be in a handlers sub-directory and follow the naming convention of
+   views handlers (ie: views_handler_field/filter/sort_handlername.inc )
+
+Views Table Definitions:
+- Please use the template files provided whenever you are describing a new table to views.
+   For any table in chado simply copy template.table_defn.views.inc to tablename.views.inc and 
+   follow the instructions listed at the top of the template file.
+- ONLY ONE TABLE DEFINITION PER FILE
+- To join a chado table to it's drupal node simply copy template.node_join.views.inc to 
+   basetablename.views.inc and replace all XXX with basetablename.
+   
+   NOTE: Creating the table definition file is not enough. You also need to call the 
+         retrieve_XXX_views_data() function from ../tripal_pub.views.inc:tripal_pub_views_data()
+         by adding the following line:
+            $data = array_merge($data, retrieve_XXX_views_data());
+         to the function and including the file directly above the function (blow the function 
+         header by adding:
+            require_once('views/XXX.views.inc');

+ *   - Every instance of XXX should be replaced with the name of your table
+ *   - If this is a base table (you want a view where every row is a row from this table)
+ *     then change $data['XXX']['table'] to $data['XXX']['table']['base'] 
+ *     and $data['XXX']['table']['database'] to $data['XXX']['table']['base']['database']
+ *   - Relationships between this table and others: YYY is the table you are trying to join to this
+ *     one. You want to join a table to this one if this table contains a foreign key to the other
+ *     table. If the join between this table and another is through a linking table
+ *     (ie: library-XXX/YYY => library_feature-XY => feature-XXX/YYY) then make the join in both
+ *     directions (ie: in the file XXX.views.inc and the file YYY.views.inc
+ *   - Create a field definition for each field in this table using the example fields already
+ *     listed. Match the type of the database field to the field definition listed below.
+ *     (ie: for a text/varchar field from the database use plain_text_field below)
+ * 
+ *  NOTE: Creating the table definition file is not enough. You also need to call the 
+ *        retrieve_XXX_views_data() function from ../tripal_stock.views.inc:tripal_stock_views_data()
+ *        by adding the following line:
+ *           $data = array_merge($data, retrieve_XXX_views_data());
+ *        to the function and including the file directly above the function (blow the function 
+ *        header by adding:
+ *           require_once('views/XXX.views.inc');
+ *
+ *  REMOVE THIS COMMENT IN THE COPY!
