+- publications is the main table containing common publication data
+- p_* tables contain additional publication data for specific types
+- l_* tables for lists (entities) such as authors, publishers, languages,..
+- l_* tables also for parent (master) publication lists
+        publication -> p_newspaperArticle -> l_newspaper
+        publication->p->journalArticle -> l_journal
+
+    book chapter -> book is excemption as we also have book type:
+
+        publication->p_book

+1. GENERAL PRINCIPLES
+2. LIST OF CALLS
+--------------------------------------------------------------------------------
+1. GENERAL PRINCIPLES
+
+1.1 SENDING REQUESTS 
+
+    Your client should request queries using a POST parameter to:
+
+    a) API URL
+
+        default: https://bibliography.europeansocialsurvey.org/api
+
+    b) an appropriate command, passed as a POST variable w
+
+    c) (optional) parameters as additional POST variables
+
+
+1.2 RECEIVING RESPONSES
+
+    In case of success, data is received along with HTTP code 200 ("OK").
+
+    In case of wrong call, http code 400 ("Invalid request") is returned.
+
+    In case of error in server side appropriate HTTP response code along with 
+        text content is returned.
+
+    In essence: check the response codes before reporting bugs!
+
+
+
+1.3 JQUERY CLIENT EXAMPLE
+
+    The following simple example requests the lists of countries and fills the 
+    according drop-down ("affiliation"). 
+
+        $.ajax ({
+            method: "POST",
+            url: API_URL,
+            data: {
+                w: 'list_countries'
+            }
+        })
+        .done (function (msg) {
+            if (msg == '') {
+                console.log('No response received from API!');
+            }
+            else {
+                $('#affiliation').html('<option value="0">Any</option>');
+
+                if (msg['status'] == "200") {
+                    msg['data'].forEach(function (item) {
+                        $('#affiliation').html( $('#affiliation').html() + '<option value="' + item['id'] + '">' + item['name'] + '</option>');
+                    });
+                }
+                else {
+                    console.log(msg);
+                }
+            }
+        })
+        .fail (function() {
+            console.log('No response received from API!');
+        });
