Hi Timothy
I find the implicit dependency control in Merlin fascinating. As a wish
list, I would very much like to be able to also have the explicit sequencing
control.
To give some idea, please see the following excerpt from a configuration
file.
Few notes about this excerpt:
1. startup: can have values automatic, manual or disabled, just like any
service in Windows or Linux
2. description: Some text that can be used by the
component/service/container to give user notification
3. name: is more or less equivalent to "type" in Merlin
4. id: is more or less equivalent to "key/source" in Merlin
5. bootSequence: pretty much primitive compared to Merlin's dependency
control, but could be an add-on to Merlin
6. groups: some times components/services like to find each other based on
groups they belong to, just like pc's in a sub-network
7. categories: another meta information that could be useful
Several of the above meta data are optional.
