=head3 Rap's Features |
95 |
|
- have targets (like make) declared in xml (like ant) |
96 |
|
- run these targets... |
97 |
|
- ... from a multitude of possible human interaction devices (HIDs), e.g. |
98 |
|
- cli (console mode) |
99 |
|
- gui |
100 |
|
- web |
101 |
|
- speech |
102 |
|
- scribe |
103 |
|
- ... from a different location (non-local - for remote administration purposes) |
104 |
|
- the remote wrapper is 'rapd' - the rap-daemon.... |
105 |
|
- rapd can run in command-mode (like apache, sendmail and related) |
106 |
|
and/or web-service mode (commands are wrapped into request-/response- |
107 |
|
xml-payload-communication) |
108 |
|
- rap is self contained on various levels |
109 |
|
- runtime-layer |
110 |
|
- pass arguments between targets |
111 |
|
- core targets are declared in xml (rap-lingo) as well |
112 |
|
these exist by now: (look at Data/Rap/targets/default.xml) |
113 |
|
- core.os.win32 |
114 |
|
- core.os.linux |
115 |
|
- core.rap.mode |
116 |
|
- core.rap.daemon |
117 |
|
- declaration-layer |
118 |
|
- the xml-file in rap-lingo can contain descriptions associated with each target |
119 |
|
- rap can make report on its guis about these |
120 |
|
- rap can use this declaration as an api for the rap-daemon 'rapd' |
121 |
|
- rap itself can run in "global"- or "project"-mode |
122 |
|
- FIXME: write something about this (by now: read the source, luke.....) |
123 |
|
|
124 |

|
=head3 Rap's Future |
126 |
|
- rapd |
127 |
|
- rapd can also run in apache mode for non-root purposes |
128 |
|
- many rapd's can talk to each other - first example application would be: |
129 |
|
- one rapd is running as apache-mod-perl-handler (non-root) |
130 |
|
- one rapd is running locally as root |
131 |
|
- remark: the way to go (by now) is via org.netfrag.glib's DataSource-libraries, |
132 |
|
which wrap the innards of rpc-communication via xml (XMLRPC) (lingo: php) |
133 |
|
an example application is caesar.rapweb and (maybe) caesar.ums |
134 |
|
|
