| 2 | |
| 3 New: | |
| 4 | |
| 5 * Two sub projects: 'artifacts' and 'artifact-database' | |
| 6 | |
| 7 - 'artifacts' is a set of generic interfaces modelling | |
| 8 the workflow to parameterize a process and producing | |
| 9 outputs. | |
| 10 | |
| 11 An artifact is created via factories. It describes | |
| 12 itself via 'describe', it is parameterized via | |
| 13 'feed' and brought to new states with 'advance'. | |
| 14 Once able to produce output 'out' returns the | |
| 15 requested product. | |
| 16 | |
| 17 - 'artifact-database' is the default implemention | |
| 18 of the workflow described with 'artifact'. | |
| 19 | |
| 20 * artifact-database persists artifacts with a H2-database | |
| 21 [http://www.h2database.com] (default) or a | |
| 22 PostgeSQL 8.3+ database [http://www.postgresql.org/] (optional) | |
| 23 | |
| 24 * artifacts may spawn background threads to copy with long running | |
| 25 processes. After finishing work they are able to re-synchronize | |
| 26 themselves to the artifact database. | |
| 27 | |
| 28 * artifact-database is accessible via an HTTP REST server | |
| 29 implemented on top of the Restlet API http://www.restlet.org/ | |
| 30 It has to be started as a service. Default TCP port: 8181 | |
| 31 | |
| 32 HTTP GET '/factories' returns list of available factories. | |
| 33 HTTP GET '/create' creates new artifact. | |
| 34 HTTP GET '/artifact/{uuid}' returns a description of an artifact. | |
| 35 HTTP POST '/artifact/{uuid}' modifies an artifact ('feed', 'advance') | |
| 36 HTTP POST '/artifact/{uuid}/{out}' delivers output for an artifact. | |
| 37 | |
| 38 * artifact-database is configured with as XML file named conf.xml | |
| 39 (default placement in directory $HOME/.artitactdb, directory | |
| 40 may be changed with system property "artifact.database.dir") |
