tim@906: \section{Model of transitions} hans@911: \subsection{Overview of Subject-Specific Configuration: From FIS, Products, States, hans@911: Transitions and SQL-statements} tim@910: hans@911: The GNV-system provides several expert information systems (FIS). Within a FIS hans@911: users can select products for analysing and visualising different hans@911: subject-specific issues like timeseries diagrams and different types of hans@911: profiles. In order to generate these products, different kind of data out of the hans@911: dataware house is needed. tim@910: hans@911: The configuration is mainly split up into two steps\footnote{Except for hans@911: integrating the MapViewer. There is a third step necessary by configuring hans@911: additional tables in the datawarehouse}: hans@911: \begin{enumerate} hans@911: \item FIS and their according products (Metainformation) tim@943: \item Products with their states, transitions, outputs and SQL-statements hans@911: (Implementation) hans@911: \end{enumerate} tim@910: tim@920: %% TODO: Add a Screenshot of the GNV WebClient marking GUI elements for FIS, hans@911: %% product, states and transitions tim@910: tim@943: Main entry point for the configuration also is the file {\tt conf/conf.xml } hans@911: defining the list of FIS and the according products based on the different tim@943: datamodels in the datawarehouse. tim@943: tim@943: The provided datamodels are: tim@910: hans@911: \begin{enumerate} hans@911: \item ESRI ArcMarineBSH with following subtypes hans@911: \begin{enumerate} hans@911: \item TimeSeriesPoints hans@911: \item MeshFeatures hans@911: \item Measurements/InstantaneousPoints tim@914: \item Marine Features hans@911: \end{enumerate} hans@911: \item ESRI ArcS57, hans@911: \item CONTIS hans@911: \end{enumerate} tim@910: hans@911: Each product configuration consists of a datamodel specific configuration tim@941: organized in a product specific folder in {\tt conf/products} \footnote{The tim@941: special case of a {\tt Horizontales Schnittprofil} is configured in tim@941: {\tt conf/horizontalprofile/conf\_mesh\_cross.xml} }. The directory layout looks hans@911: like this: hans@911: hans@911: \begin{verbatim} hans@911: products/ hans@911: |-- horizontalcrosssection hans@911: | `-- conf_mesh.xml hans@911: |-- horizontalprofile hans@911: | |-- conf_instantaneouspoint.xml hans@911: | |-- conf_mesh.xml hans@911: | `-- conf_mesh_cross.xml hans@911: |-- layer hans@911: | `-- conf.xml hans@911: |-- timeseries hans@911: | |-- conf_mesh.xml hans@911: | |-- conf_timeseriespoint.xml hans@911: | `-- timegap_definition.xml hans@911: |-- verticalcrosssection hans@911: | `-- conf_mesh.xml hans@911: `-- verticalprofile hans@911: |-- conf_instantaneouspoint.xml hans@911: |-- conf_mesh.xml hans@911: `-- conf_timeseriespoint.xml hans@911: \end{verbatim} hans@911: hans@911: The subtypes of the ArcMarineBSH based datamodel are configured in the files below: tim@910: \begin{itemize} tim@941: \item TimeSeriesPoints: {\tt conf\_timeseriespoint.xml} tim@941: \item Mesh: {\tt conf\_mesh.xml} tim@941: \item InstantaneousPoints: {\tt conf\_instantaneouspoint.xml} tim@910: \end{itemize} tim@910: hans@911: Within each of these files, the steps for gathering the values for the hans@911: parameterisation are configured by defining states, transitions and outputs tim@920: (c.f. \ref{ref:config-a-product}). The definition of states, transitions and hans@931: outputs reference the actual SQL-statements via an identifier. The SQL-statements tim@941: are gathered in the file {\tt conf/queries.properties}. hans@911: tim@910: hans@931: \subsection{Explaining the background of the XML configuration} tim@907: tim@908: It is possible to configure the GNV in many ways. tim@940: It is possible to add or remove FIS, add or remove products from a FIS or tim@908: to manipulate the steps which must be gone until a product can be create tim@940: a diagram or generate an CSV-export. tim@908: tim@920: The configuration of the provided FIS are divided in three main parts. tim@908: tim@908: \begin{itemize} tim@941: \item Configuration of the list of FIS via {\tt artifact-factories} tim@941: \item Configuration of main {\tt artifacts} which will be instantiated if an tim@941: {\tt artifact-factory} was called. tim@941: \item Configuration of the different {\tt artifacts} which provides products which can be tim@907: served by the FIS. tim@908: \end{itemize} tim@907: tim@910: \subsubsection{Configuration of a FIS} tim@941: The point of entry into the system is to configure an {\tt artifact-factory}. tim@941: Each {\tt artifact-factory} represents one FIS. tim@941: It is possible to configure several {\tt artifact-factories}. tim@941: The {\tt artifact-factories} will be configured in the section tim@941: {\tt /artifact-database/artifact-factories} of the configurationfile. tim@907: tim@907: \begin{lstlisting} hans@931: tim@907: de.intevation.gnv.artifacts.GNVProductArtifactFactory tim@907: tim@907: \end{lstlisting} tim@907: tim@941: At this moment the following attributes of an {\tt artifact-factory} are configurable. tim@908: \begin{itemize} tim@941: \item {\tt name}: The name of the {\tt artifact}.

To create this {\tt artifact} we have to tim@941: use an {\tt artifact-factory} which is configured in each product tim@941: ({\tt /product/artifact-factory}). tim@907: tim@941: Each product can have several parameters ({\tt /product/parameters/parameters}). tim@941: The {\tt parameter} named {\tt sourceid} and {\tt fisname} are required parameters. tim@907: tim@941: The parameter {\tt fisname} contains the key to the name of the FIS. The key must be tim@907: unique. tim@941: The parameter {\tt sourceid} contains the key to identify the FIS in the tim@941: datawarehouse. ({\tt MEDIAN.SOURCEINFO}) tim@907: tim@907: tim@910: \subsubsection{Configuration of an Product} hans@911: \label{ref:config-a-product} tim@941: The {\tt products} of the different FIS are also modeled as artifact-objects. tim@940: The different products which are currently available are stored in separate tim@941: files in the folder {\tt project}. tim@908: tim@940: In those files the workflow of each product is configured. Each step which is tim@941: required to model a new diagram is represented using a {\tt state} in the tim@940: configurationfile. tim@908: tim@941: To move between those {\tt states} it is required to model {\tt transitions} which define tim@940: between which states it is possible to move and which conditions must be tim@908: fulfilled. tim@908: tim@941: The last step is called {\tt output-state}. This state is responsible to generate the tim@941: output for the different formats which can be served from the product ({\tt Diagram, tim@941: CSV, ODV, WMS,..}.). tim@908: tim@907: \paragraph{States} tim@941: A {\tt state} is one step which is required to fetch the data for generating e.g. an tim@940: diagram. tim@908: tim@940: For example in each product it is possible to choose one or more parameters. tim@908: tim@940: To configure a state you have to use a XML-fragment as shown below: tim@908: tim@908: \begin{lstlisting} tim@908: tim@908: timeseries_parameter tim@908: parameterid tim@908: true tim@908: tim@913: ... tim@908: tim@908: tim@908: \end{lstlisting} tim@908: tim@941: At this moment the following attributes of an {\tt state} are configurable. tim@908: \begin{itemize} tim@941: \item {\tt id}: The name of the artifact.

This will be done using the configuration for tim@941: an FIS which use data from {\tt MEDIAN.TIMESERIES} section of the datawarehouse e.g. tim@908: MARNET or STAUN tim@906: tim@941: Pay attention that for publishing the changes to the {\tt artifact-server} you will tim@906: have to restart it. tim@906: tim@940: \subsubsection{Adding a new Artifact-factory} tim@941: First step is to add a new {\tt artifact-factory} to the configuration conf/conf.xml tim@940: To do this you have to add a new XML-fragment into the section tim@906: /factories/artifact-factories which look like that: tim@906: tim@906: \begin{lstlisting} tim@906: tim@906: de.intevation.gnv.artifacts.GNVProductArtifactFactory tim@906: tim@906: \end{lstlisting} tim@906: tim@941: In this XML-fragment you only have to replace the placeholder {\tt NEWFISNAME} tim@941: with a unique short name for the new FIS. tim@906: tim@916: \paragraph{Example} tim@940: This example shows how to add an FIS and which effects it took to the tim@916: REST-Server. tim@916: tim@941: At first we add the following {\tt artifact-factory} into the file tim@941: {\tt conf/conf.xml} in section {\tt /artifact-database/artifact-factories} tim@941: which add a new FIS called {\tt justanewfis} to the server: tim@916: tim@916: \begin{lstlisting} tim@916: tim@916: de.intevation.gnv.artifacts.GNVProductArtifactFactory tim@916: tim@916: \end{lstlisting} tim@916: tim@941: Then we restart the {\tt artifact-database} executing the following command: tim@916: tim@920: \begin{lstlisting} tim@916: /etc/init.d/artifactdb restart tim@920: \end{lstlisting} tim@916: tim@916: Then we check if the new FIS is served by the REST-Server tim@916: calling the following command: tim@916: tim@920: \begin{lstlisting} tim@919: curl http://localhost:8181/factories | xmllint --format - | grep fis\_justanewfis tim@920: \end{lstlisting} tim@916: tim@941: If the FIS was added the new {\tt artifact-factory} will be found in the generated tim@940: XML-output and it will be shown. tim@940: Otherwise no XML-output will be shown. tim@916: tim@940: \subsubsection{Adding a new Artifact for Artifact-factory} tim@940: The next step is to define the artifact itself. tim@941: For this it is necessary to add an XML-fragment into the section tim@941: {\tt /artifacts} of the main configurationfile {\tt /conf/conf.xml}. tim@941: tim@906: \begin{lstlisting} tim@906: tim@906: tim@906: ... tim@906: tim@906: tim@906: \end{lstlisting} tim@906: tim@941: In this XML-fragment it is also required to replace the placeholder {\tt NEWFISNAME} tim@941: with the name which was used to configure the {\tt artifact-factory}. tim@906: tim@941: Now the {\tt artifact-server} can handle an additional FIS without any products yet. tim@906: tim@940: To prevent needless configuration-work it is useful way to clone an artifact tim@940: which handle the same kind of work as the new FIS. tim@906: tim@917: tim@917: \paragraph{Example} tim@940: Now we will configure an artifact to the FIS justanewfis. tim@917: tim@941: For this we have to add the following XML-fragment to the file tim@941: {\tt conf/conf.xml} in section {\tt /artifact-database/artifacts}: tim@917: tim@917: \begin{lstlisting} tim@917: tim@917: tim@917: tim@917: tim@917: \end{lstlisting} tim@917: tim@940: Restart the artifact-database: tim@917: tim@919: \begin{lstlisting} tim@917: /etc/init.d/artifactdb restart tim@919: \end{lstlisting} tim@917: tim@940: Now we should be able to choose the artifact. tim@919: tim@917: The Listbox with products will be empty. tim@919: \begin{lstlisting} tim@919: curl -d "@sample-documents/create-artifact.xml" http://localhost:8181/create | xmllint --format - tim@919: \end{lstlisting} tim@917: tim@906: \subsubsection{Adding removing Products to the specific Artifact} tim@940: Now it is time to configure the different products which the FIS should be able tim@906: to provide. tim@940: To do this it is necessary to copy the XML-fragments of the products into the tim@941: XML-element {\tt products} of the previously integrated artifact. tim@906: \begin{lstlisting} tim@906: tim@906: tim@906: tim@906: tim@906: de.intevation.gnv.artifacts.GNVArtifactFactory tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: de.intevation.gnv.artifacts.GNVArtifactFactory tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: \end{lstlisting} tim@906: tim@941: In this XML-fragment you have to replace the placeholders {\tt NEWFISNAME} tim@941: as before and {\tt VALUEOFSOURCEID} with the value for the new FIS as defined tim@941: in the table {\tt MEDIAN.SOURCEINFO}. tim@906: tim@918: \paragraph{Example} tim@940: Now we will add a product to the new FIS. tim@940: To let the products work we will choose a product which tim@918: will contain the sourceid of an existing FIS (e.g 4 Marnet). tim@918: tim@940: At first add the following XML-fragment to the new artifact. tim@918: \begin{lstlisting} tim@918: tim@918: tim@918: de.intevation.gnv.artifacts.GNVArtifactFactory tim@918: tim@918: tim@918: tim@918: tim@918: tim@919: tim@918: \end{lstlisting} tim@918: tim@940: Restart the artifact-database: tim@918: tim@919: \begin{lstlisting} tim@918: /etc/init.d/artifactdb restart tim@919: \end{lstlisting} tim@919: tim@919: If we call tim@919: \begin{lstlisting} tim@919: curl -d "@sample-documents/create-artifact.xml" http://localhost:8181/create | xmllint --format - tim@919: \end{lstlisting} tim@919: tim@941: the product {\tt timeSeries} should be available for the FIS {\tt justanewfis}. tim@918: tim@940: Now we should be able to choose the product. tim@940: This product should work and you should be able to generate even the defined tim@940: outputformats. tim@918: tim@906: \subsection{Adding a new Product} tim@940: To add a new product to the system it is necessary that the required tim@941: artifact representation is implemented in the {\tt sourcecode}. tim@940: Without doing that step it is not possible to create a new product. tim@906: tim@940: All products are configured in separate files that will be included into the tim@940: main configuration using Xlink-references. tim@906: tim@941: First step is to create a new file in the folder {\tt products} and there in the tim@941: sub-folder where the product belongs to ({\tt timeseries,verticalprofile, tim@941: horizontalprofile,horizontal\-crosssection,layer,...}) tim@906: tim@941: Then you have tor reference this file in the file {\tt /conf/conf.xml} in the tim@941: section {\tt/artifacts} using the following XML-fragment. tim@906: tim@906: \begin{lstlisting} tim@906: tim@906: \end{lstlisting} tim@906: tim@941: The placeholder {\tt PATHTOFILE} has to be replaced with the relative path and tim@941: the name of the file starting in the folder products. tim@906: tim@906: Then it is possible to add the product to a FIS as explained in the next section. tim@941: Please note that the defined name of the {\tt artifact-factory} has to match to the tim@940: name of the added products which is also designed as an artifact. tim@906: tim@906: \subsection{Adding a additional Product to a FIS} tim@940: To add a additional product to a FIS you only have to add the XML-fragment which tim@940: represents the product to the artifact-configuration of the FIS in section tim@941: {\tt /artifacts/artifact/products}. tim@906: tim@906: \begin{lstlisting} tim@906: tim@906: tim@906: de.intevation.gnv.artifacts.GNVArtifactFactory tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: tim@906: \end{lstlisting} tim@906: tim@906: Please note that you have to replace the Placeholders as explained above. tim@906:
