First of all, we can recommend to use Eclipse (version Luna for example). You will need the Maven extension.
Import the B-HIT project in B-HIT (File/New/Maven Project -> put the location of the directory where you downloaded B-HIT).

Add an simple element (ie. it can be added to an existing table in the database)

1. Choose where you want to save it

Add a repeatable or a more complex element or group of elements (ie. it will need a new table in the database)

1.Choose where you want to save it Example: add a reference group (ABCD2.06) http://www.bgbm.org/tdwg/codata/schema/ABCD_2.06/HTML/ABCD_2.06.html#complexType_Reference_Link031A69A8 A Reference is made of 3 elements: TitleCitation, CitationDetail and URI. As a Reference can be linked to several ABCD concepts, it might make more sense to link the Reference(s) to the concept than to the whole Unit

A) Create a new table in the database for the references, with an auto-incrementation ID. Put a new empty line (referenceID 1, titleCitation null, citationDetail null, URI null) because you will need a foreign key to make the rest easier. B) Add a new column in the table from the concept that will have a Reference (ie. fk_referenceID), and configure it as a foreign-Key with the default value 1 for all the old records) C) Document the file with the "SQL changes". D) Edit the Java code!

• Have a look at the src/org/binhum/abcd/Multimedia.java class. The new class could look like this:

package org.binhum.abcd;

import java.util.Map;

import org.dom4j.Document;

import com.mysql.jdbc.StringUtils;


public class Reference extends XMLutil {

   private static final long serialVersionUID = 2096267214610763427L;
   private String URI;
   private String title;
   private String detail;
   private String standard; //abcd or abcd21
   
   private Map<String, String> namespaceMap;
   private Document xmlDocument;
   
   Reference(Map<String, String> namespaceMap, String standard) {
       this.namespaceMap=namespaceMap;
       this.standard=standard;
   }
   /**
    * @return the uRI
    */
   public String getURI() {
       return URI;
   }
   /**
    * @param uRI the uRI to set
    */
   public void setURI(String uRI) {
       URI = uRI;
   }
   /**
    * @return the title
    */
   public String getTitle() {
       return title;
   }
   /**
    * @param title the title to set
    */
   public void setTitle(String title) {
       this.title = title;
   }
   /**
    * @return the detail
    */
   public String getDetail() {
       return detail;
   }
   /**
    * @param detail the detail to set
    */
   public void setDetail(String detail) {
       this.detail = detail;
   }
   public Document getXmlDocument() {
       return xmlDocument;
   }
   public void setXmlDocument(Document xmlDocument) {
       this.xmlDocument = xmlDocument;
       detail = getTextValue(xmlDocument, "//"+standard+":Reference/"+standard+":CitationDetail", namespaceMap);
       title=getTextValue(xmlDocument, "//"+standard+":Reference/"+standard+":TitleCitation", namespaceMap);
       URI=getTextValue(xmlDocument, "//"+standard+":Reference/"+standard+":URI", namespaceMap);
   }
}

• Save the new Reference and get it ID (ie. referenceid= occurrenceDao.createOrUpdateReference(referenceObj);

--> create the createOrUpdateReference method in org/binhum/harvest/util/jdbc/dao/OccurrenceDao.java (abstract) and org/binhum/harvest/util/jdbc/dao/OccurrenceDaoImpl.java

• Have a look at the class of concept you want to link it to.
• Add this ID to the concept you want to link it to, usually in the Unit.java class (for example:

    Preparation prepa = new Preparation();
    prepa.setTripleidstoreid(triplestoreid);
    prepa.setPreparationDate(extractionDate);
    prepa.setPreparationStaff(extractionStaff);
    prepa.setPreparationMaterials(extractionMethod);
    prepa.setPreparationType(preparationType);
    prepa.setReferenceid(referenceid);
    savePreparation(prepa);

-> You will have to create the method setReferenceid and getReferenceid in the class Preparation.java. !! For each concept, reset the referenceID first to 1, or you might have the reference from a previous element attached to the current concept !! Also, you have to update the savePreparation method (ie. occurrenceDao.createOrUpdatePreparation(prepa); ie. you will have to edit in the OccurrenceDaoImpl.java class following elements:

*createPreparation : add a ps.setInt(6, prepa.getReferenceid()); 
*CREATE_PREPA_SQL : add the table column and a question mark for the SQL statement
*UPDATE_PREPA_SQL : add the table column with the question mark for the SQL statement
*createOrUpdatePreparation : add ps.setInt(6, prepa.getReferenceid()); and change ps.setInt(6, prepa.getId()); to ps.setInt(7, prepa.getId());

!! Check the field order and the number of fields/columns !!

• delete by updates!

Add a new data standard
