+======Serials Checkin and Pattern Maintenance - some notes======
+//These is a proposed implementation at this point, serials may not necessarily work like this//
+Serials maintenance is handled under //subscriptions//, which is associated with a start date.
+{{:acq:serials:sub1.jpg|Subscription Screen}}
+The //cycles// that identify a pattern for a serial are defined individually, and a notes field is available for adding explanatory text if desired.
+{{:acq:serials:ser2.jpg|Cycles Screen}}
+The recurrence definition is handled as an expandable list of options, and exceptions are associated with predefined calendars. So, for example, if a library does count holidays in determining whether a serial claim is warranted, one calendar can maintain this information. Further exceptions can also be placed when the cycle is associated with a subscription.
+{{:acq:serials:ser3.jpg|Subscription Cycles Screen}}
+Any number of cycles can be associated with a subscription. A //claim delay// is used to identify the period of time to wait before initiating a claim. Addition exceptions can also be made using a calendar associated with this instance of the cycle. If a cycle is defined for a virtual resource, an option is to identify a web mechanism for checking the title's availability. Claims are identified by the //job scheduler//, which runs daily or more frequently if desired.
+The job scheduler uses an [[http://en.wikipedia.org/wiki/ICalendar|iCal]] rule structure. The service logic looks like:
+  //work out permissions
+  GenericDelegator delegator = dctx.getDelegator();
+  LocalDispatcher dispatcher = dctx.getDispatcher();
+  GenericValue userLogin = (GenericValue) context.get("userLogin");
+  Security security = dctx.getSecurity();
+  Locale locale = (Locale) context.get("locale");
+  if (! security.hasEntityPermission("ACCOUNTING", "_ATX_POST", userLogin)) {
+    return ServiceUtil.returnError(UtilProperties.getMessage("FinancialsUiLabels",
+      "FinancialsServiceErrorNoPermission", locale));
+  }
+  //check patterns
+  List transactions = null;
+  try {
+    List conditions = UtilMisc.toList(
+      new EntityExpr("scheduledReceiveDate", EntityOperator.NOT_EQUAL, null),
+      new EntityExpr("scheduledReceiveDate", EntityOperator.GREATER_THAN_EQUAL_TO,
+      UtilDateTime.nowTimestamp()),
+      new EntityExpr("isReceived", EntityOperator.EQUALS, "N")
+    );
+    transactions = delegator.findByAnd("SerialsTrans", conditions);
+  } catch( GenericEntityException e ) {
+    Debug.logError(e.getMessage(), module);
+    return ServiceUtil.returnError(e.getMessage());
+  }
+  //invoke service to deal with titles due to be received
+  Map input = UtilMisc.toMap("userLogin", userLogin);
+  for (Iterator iter = transactions.iterator(); iter.hasNext(); ) {
+    GenericValue transaction = (GenericValue) iter.next();
+    input.put("serialsTransId", transaction.get("serialsTransId"));
+    try {
+      Map results = dispatcher.runSync("dealWithMissedSerialsTrans", input);
+      if (ServiceUtil.isError(results)) {
+        Debug.logError("Failed to process SerialsTransaction ["+
+          transaction.get("serialsTransId")+"] due to logic error: " +
+          ServiceUtil.getErrorMessage(results), module);
+      }
+    } catch( GenericServiceException e ) {
+      Debug.logError(e, "Failed to post scheduled SerialsTransaction ["+
+        transaction.get("serialsTransId")+"] due to service engine error: " +
+        e.getMessage(), module);
+    }
+  }
+  return ServiceUtil.returnSuccess();
