How can I add components to the ACS CDB without modifying $ACS_CDB/MACI/Components/Components.xml?

Instead of just having one file, Components.xml, in your CDB you now have the option to replace it with a separate directory which 
includes a single xml file "for each component entry". To allow this ACS has added an additional schema, Component.xsd (notice this 
schema is for a single component), to be used instead of the Components.xsd schema that the Components.xml file uses currently. 

For example:
If you previously had:

$ACS_CDB/CDB/MACI/Components/Components.xml

Where the Components.xml file looked as follows:

<?xml version="1.0" encoding="utf-8"?>
<Components  xmlns="urn:schemas-cosylab-com:Components:1.0"
         xmlns:cdb="urn:schemas-cosylab-com:CDB:1.0"
         xmlns:baci="urn:schemas-cosylab-com:BACI:1.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >

       <_ Name="MOUNT1"      Code="acsexmplMountImpl"
                             Type="IDL:alma/MOUNT_ACS/Mount:1.0"
                             Container="bilboContainer"/>
       <_ Name="MOUNT2"      Code="acsexmplMountImpl"
                             Type="IDL:alma/MOUNT_ACS/Mount:1.0"
                             Container="bilboContainer"/>
       <_ Name="HELLODEMO1"  Code="alma.demo.HelloDemoImpl.HelloDemoHelper"
                             Type="IDL:alma/demo/HelloDemo:1.0"
                             Container="frodoContainer"/>
       <_ Name="HELLOLAMP1"  Code="alma.demo.LampAccessImpl.LampAccessHelper"
                             Type="IDL:alma/demo/LampAccess:1.0"
                             Container="frodoContainer"/>

</Components>

The new CDB structure you would have would look like:

 $ACS_CDB/CDB/MACI/Components/MOUNT1/MOUNT1.xml

 $ACS_CDB/CDB/MACI/Components/MOUNT2/MOUNT2.xml

 $ACS_CDB/CDB/MACI/Components/HELLO1/HELLO1.xml

 $ACS_CDB/CDB/MACI/Components/HELLO2/HELLO2.xml

 
An example of the xml file would be 

(C++ example for the MOUNT1.xml)

<?xml version="1.0" encoding="utf-8"?>
<Component  xmlns="urn:schemas-cosylab-com:Component:1.0"
       xmlns:cdb="urn:schemas-cosylab-com:CDB:1.0"
       xmlns:baci="urn:schemas-cosylab-com:BACI:1.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            Name="MOUNT1"
            Code="acsexmplMountImpl"
            Type="IDL:alma/MOUNT_ACS/Mount:1.0"
            Container="bilboContainer"
/>

(Java example for HELLO1.xml)

<?xml version="1.0" encoding="utf-8"?>
<Component  xmlns="urn:schemas-cosylab-com:Component:1.0"
       xmlns:cdb="urn:schemas-cosylab-com:CDB:1.0"
       xmlns:baci="urn:schemas-cosylab-com:BACI:1.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            Name="HELLODEMO1"  
            Code="alma.demo.HelloDemoImpl.HelloDemoHelper"
            Type="IDL:alma/demo/HelloDemo:1.0"
            Container="frodoContainer"
/>
 

Important things to note: 

1. The component�s xml filename must match the directory name which it is in.
   For example, if you create $ACS_CDB/CDB/MACI/Components/COMP1, the xml file must be called COMP1.xml 

2. Some components, particularly C++ components, require instance xml files.  This is usually associated 
   with components which use properties.  In this case the file hierarchy in the $ACS_CDB/CDB/MACI/Components 
   directory and the $ACS_CDB/alma directory must match. 

          For example if you have 

               $ACS_CDB/CDB/MACI/Components/MOUNT1/MOUNT1.xml 

          then you must have 

               $ACS_CDB/CDB/alma/MOUNT1/MOUNT1.xml

   If you are not using properties in C++ you do not need to do this because you do not have an entry in 
   $ACS_CDB/CDB/alma. Likewise for Java components or Python components, which usually do not require 
   properties, you can call the new directory and xml file anything you want.
