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:
hans@947: %% TODO to improve: 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@947: \subsection{Background information 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
hans@947: to manipulate the steps which must be prepared until products like
hans@947: a diagram or CSV-export can be generated.
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}.
hans@947: Each artifact-factory represents one FIS.
hans@947: It is possible to configure several {\tt artifact-factories}, which
hans@947: represent the list of FIS in GUI.
tim@941: The {\tt artifact-factories} will be configured in the section
hans@948: \texttt{/artifact-database/artifact-factories} of the configuration-file.
tim@907:
tim@907: \begin{lstlisting}
hans@931:
tim@907: de.intevation.gnv.artifacts.GNVProductArtifactFactory
tim@907:
tim@907: \end{lstlisting}
tim@907:
hans@947: At this moment the following attributes of an {\tt artifact-factory} are
hans@947: configurable:
tim@908: \begin{itemize}
tim@941: \item {\tt name}: The name of the {\tt artifact}. Must be unique in one {\tt artifact-server}
tim@941: \item {\tt description}: Short description which job the {\tt artifact-factory} has to do.
hans@947: \item {\tt ttl}: The time to live: The time using milliseconds an
hans@947: {\tt artifact}, created using this factory, can live without any
hans@947: user-interaction.
tim@941: \item {\tt artifact}: The name of the class of the {\tt artifact} which should be created.
tim@908: \end{itemize}
tim@907:
tim@940: The next listing shows the dependencies between the FIS and the name
tim@941: of the {\tt artifact-factory} which belongs to it.
hans@911:
hans@911: \begin{itemize}
tim@941: \item Marnet: {\tt fis\_marnet}
tim@941: \item IMIS: {\tt fis\_imis}
tim@941: \item STAUN: {\tt fis\_staun}
tim@941: \item Modeldata {\tt fis\_modeldata}
tim@941: \item Iceclimatology: {\tt fis\_eisklimatologie}
tim@941: \item Ice Station Report: {\tt fis\_icestations}
tim@941: \item SST: {\tt fis\_sst}
tim@941: \item Delphin: {\tt fis\_delphin}
tim@941: \item Thermosalinograph: {\tt fis\_thermosalinograph}
tim@941: \item Chemusurvey: {\tt fis\_chemusurvey}
tim@941: \item GTS: {\tt fis\_gts}
tim@941: \item CTD: {\tt fis\_bsh\_ctd}
tim@941: \item XBT: {\tt fis\_bsh\_xbt}
tim@941: \item SeaCat: {\tt fis\_seacat}
tim@941: \item Sea State: {\tt fis\_seastate}
tim@941: \item Current Meter: {\tt fis\_currentmeter}
tim@941: \item Nauthis: {\tt fis\_nauthis}
tim@941: \item Contis: {\tt fis\_contis}
tim@941: \item Marine Features: {\tt fis\_marinefeatures}
hans@911: \end{itemize}
hans@911:
tim@907: \subsubsection{Configuration of main Artifact}
tim@941: For each {\tt artifact-factory} it is necessary to configure one {\tt artifact} which will be
tim@940: created using the factory.
tim@941: This {\tt artifact} is the representation of the specific FIS.
tim@940: It contains the configuration which products will be served for this FIS.
tim@907:
tim@941: The {\tt artifacts} are configured in the section {\tt /artifact-database/artifacts} of
tim@940: the configurationfile.
tim@907:
tim@907: \begin{lstlisting}
hans@931:
tim@907:
tim@907: ...
tim@907:
tim@907:
tim@907: \end{lstlisting}
tim@907:
tim@941: The key is to use the same name for the {\tt artifact} as used for the {\tt artifact-factory}.
tim@940: The name has to be unique.
tim@941: In the section {\tt /artifact/products} it is possible to define several products as
tim@940: explained in the next section.
tim@907:
hans@947: \subsection{Products to an FIS}
tim@940: One FIS can provide several products.
tim@940: To do this it is required to configure them as shown below in the section
tim@941: {\tt /artifact/products}
tim@907:
tim@907: \begin{lstlisting}
tim@907:
tim@907:
tim@907: de.intevation.gnv.artifacts.GNVArtifactFactory
tim@907:
tim@907:
tim@907:
tim@907:
tim@907:
tim@907:
tim@907: \end{lstlisting}
tim@907:
hans@947: Each {\tt product} is also represented by an {\tt artifact}. In order to
hans@947: create this {\tt artifact}, the {\tt artifact-factory} has to be used.
hans@947: It is configured in each product
tim@941: ({\tt /product/artifact-factory}).
tim@907:
hans@947: Each product can have several parameters ({\tt
hans@947: /product/parameters/parameters}). The {\tt parameter} named {\tt
hans@947: sourceid} and {\tt fisname} are required parameters.
tim@907:
hans@947: The parameter {\tt fisname} contains the key to the name of the FIS. The
hans@947: key must be unique. The parameter {\tt sourceid} contains the key to
hans@947: identify the FIS in the 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
hans@947: configuration-file.
tim@908:
hans@947: %% FIXME: fix wording
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. Must be unique in one artifact-server
tim@941: \item {\tt description}: Short description which job the artifact-factory has to do.
tim@941: \item {\tt queryID}: The id of the query which should be used to fetch the data
tim@940: displayed in this state. All queries are defined in the file
tim@920: conf/queries.properties
tim@941: \item {\tt dataname}: The id of the data which will be displayed in this state.
tim@940: The id will be use to localize the description of the data.
tim@940: The localization is located in module gnv-artifacts in folder
tim@934: src/main/resources.
tim@941: \item {\tt data-multiselect}: {\tt true} it is possible to select 1 or more items.
tim@941: {\tt false} it is possible to select only one item.
tim@941: \item {\tt inputvalues}: The values which can be "feed" to this state and which
tim@940: will be used as values in SQL-statements.
tim@909: \end{itemize}
tim@908:
tim@913: \paragraph{Input Values of a State}
tim@941: At section {\tt /state/inputvalues} it is possible to add definitions for inputvalues.
tim@941: Those values have two meanings for the {\tt state}.
tim@913:
tim@913: \begin{itemize}
tim@940: \item They were used to fill the SQL-statements to fetch the data.
tim@913: (Each entry replace one ore more "?" )
tim@940: \item They were used to validate the inputdata which is "feed" to
tim@940: the FIS in the current state.
tim@913: \end{itemize}
tim@913:
hans@947: {\bf WARNING: The order of the input-values is significant at which position the value will
hans@947: be put into the SQL-statement!}
tim@913:
tim@940: It is possible to add one inputvalue twice or more often to put its value at
tim@920: different positions of the SQL-statement.
tim@913:
tim@913: \begin{lstlisting}
tim@913:
tim@913:
tim@913:
tim@913:
tim@913:
tim@913: \end{lstlisting}
tim@913:
tim@913: \begin{itemize}
tim@941: \item {\tt name}: Name of the value that could be feed or should be used in SQL-statment.
tim@940: The name must fit to one dataname configured in this state or one other
tim@940: state which was visited before.
tim@941: \item {\tt type}: The type of the value. This is required for the validation
tim@940: of the value.
tim@913: This might be String, Integer, Double, Date, Point, LineString,
hans@945: Polygon, Coordinate, Geometry and AttributeName. \\
tim@940: Coordinate is a format which accepts geographical coordinates in
hans@945: the following Syntax: 56n30 6e20 \\
tim@940: AttributeName marks a stringvalue which will be used in
tim@940: SQL-statement without surrounding with "'" in the statement.
tim@940: Usage is e.g. for determining the Axis (i or j) in the workflow
tim@940: of Horizontalprofiles.
tim@941: \item {\tt multiselect}: true if more than on value can be feed or put into the SQL-statement.
tim@940: false if one on value will be accepted.
tim@941: \item {\tt usedinquery}: Number how often the value should be put into the SQL-statement:
tim@940: 0: Value will not out into the statement.
tim@940: 1: Value will put once into the statement,
tim@913: 2 or more: Value will be put as often as configured
tim@940: into the SQL-statement (this is useful if
tim@940: inner-selects are used)
tim@913: \end{itemize}
tim@913:
tim@913: The next part will explain the usage of inputvalues.
tim@913:
tim@940: This SQL-statement is configured to use in the state above, which will fetch
tim@940: all parameter-ids with the according german name which are reffered to the given
tim@934: TimeSeriesPoint (e.g.Arkona Basin Buoy FeatureID = 100011 )

tim@913:
hans@947: Including inputvalues, the example for choosing the FIS ({\tt fisname})
hans@947: and the Station 342 ({\tt featureid}: Arkona Basin Buoy) will look like
hans@947: this:
tim@913: \begin{itemize}
hans@947: \item {\tt featureid}: 100011 (Marnet $\rightarrow$ Arkona Basin Buoy)
tim@941: \item {\tt fisname}: fis\_marnet

tim@913: \end{lstlisting}
tim@913:
tim@941: The value of {\tt featureid} will be inserted into the query because
tim@941: the attribute {\tt usedinquery} is set to "1".
tim@913:
tim@941: The values of the inputvalues {\tt fisname} and {\tt parameterid} will be
tim@941: excluded because the attribute {\tt usedinquery} is set to "0"

tim@942: All queries will be handle using the prepared-statement-syntax using "?"
tim@942: to define a place where an dynamic value should be placed into the statement.
tim@942:
tim@942: There is one special implementation to support spatial access to the
hans@947: {\tt ESRI ArcSDE}-database. This mechanism is used to realize the access to spatial-
tim@942: objects.
tim@942:
hans@947: All queries containing the following literals will be handled separatly
hans@947: using the ESRI ArcSDE-API.
tim@942:
tim@942: \begin{itemize}
tim@942: \item {\tt ST\_ASTEXT(SHAPE)}: Will return the geometry as an WellKnowText (WKT)

tim@907: \paragraph{Transitions}
tim@908:
hans@947: To move between two states it is necessary to configure dependencies
hans@947: between the different states. This dependencies are called {\tt
hans@947: transitions}.
tim@908:
tim@941: There are different kinds of {\tt transitions} which can be used.
tim@908: \begin{itemize}
tim@940: \item Transitions which only link two states
tim@940: \item Transition which link two states with a additional condition.
tim@908: (e.g. If a region was selected in the Regionfilter or not )

tim@907: \paragraph{Outputstate}
tim@907:
hans@947: The {\tt outputstate} is a special {\tt state} which was created to define
tim@940: the different possibilities of outputs for each product.
hans@947: An {\tt outputstate} is handled as a {\tt state} which is described above.
tim@909: Additionally you are able to configure which kind of outputs should
tim@909: be provided.
tim@909:
tim@941: There are several {\tt outputstates}. Each one is designed to create
tim@940: the output for one special product.
tim@909:
tim@915: \begin{itemize}
tim@941: \item TimeSeries: {\tt TimeSeriesOutputState}
tim@941: \item Horizontalprofile: {\tt HorizontalProfileOutputState}
tim@941: \item Horizontalprofile on Meshes: {\tt HorizontalProfileMeshOutputState}
tim@941: \item Verticalcrosssection: {\tt VerticalCrossSectionOutputState}
tim@941: \item Verticalprofiles: {\tt VerticalProfileOutputState}
tim@941: \item Horizontalcrosssections: {\tt HorizontalCrossSectionMeshOutputState}
tim@941: \item Layer: {\tt LayerOutputState}
tim@915: \end{itemize}
tim@915:
tim@941: All these outputstates are implemented in {\tt package de.intevation.gnv.state}
tim@941: and its {\tt sub\-packages}.
tim@915:
hans@947: The fullqualified name of the {\tt outputstate} to the attribute
hans@947: {\tt state} is shown below.
tim@909:
hans@947: An example for an {\tt outputstate}:
tim@909:
tim@909: \begin{lstlisting}
tim@909:
tim@909: timeseries_chart_data
tim@909: ...
tim@909:
tim@909:
tim@909: ...
tim@909:
tim@909:
tim@909:
tim@909: \end{lstlisting}
tim@909:
tim@941: At section {\tt /state/outputsModes} it is possible to add one ore more
tim@941: {\tt outputmodes} to one state as shown in the next paragraph.
tim@909:
tim@909: \paragraph{OutputModes}
tim@909:
tim@941: It is possible to configure several {\tt outputmodes} in one {\tt outputstate}.
hans@947: Inserting or deleting the configuration of a special
hans@947: {\tt outputmode} will control if an item in the GUI will be displayed.
tim@909:
hans@947: {\bf
tim@909: WARNING: IT MIGHT BE POSSIBLE THAT ONE OR MORE OUTPUTMODES ARE NOT
tim@909: SUPPORTED BY AN PRODUCT. IN THAT CASE IT IS NECESSARY TO
tim@909: IMPLEMENT THE REQUIRED FUNCTIONALITY BEFORE IT IS POSSIBLE
tim@909: TO OFFER THIS OUTPUTMODE.
hans@947: }
tim@909:
tim@941: Currently the following {\tt outputmodes} are supported:
tim@909:
tim@909: \begin{itemize}
tim@941: \item {\tt chart}
tim@941: \item {\tt histogram}
tim@941: \item {\tt csv}
tim@941: \item {\tt odv}
tim@941: \item {\tt statistics}
tim@941: \item {\tt wms}
tim@941: \item {\tt shapefile}
tim@909: \end{itemize}
tim@909:
tim@941: The following example shows how to configure an {\tt outputmode chart}:

tim@941: is used by the program.
tim@941: \item {\tt description}: a short description of this outputmode.
tim@941: \item {\tt parameters}: one ore more parameters which will be shown in the
tim@941: GUI e.g. for changing the size of an chart.
tim@941: \item {\tt exportModes} : one or more formats which can be served.

hans@947: \section{Adding a new FIS}
hans@947: In this section it will be explained which steps have to be done to integrate a
tim@941: new FIS into the {\tt artifact-server}. This will be done using the configuration for
hans@947: a FIS which uses data from the table {\tt MEDIAN.TIMESERIES} section of
hans@947: the datawarehouse (e.g. MARNET or STAUN).
tim@906:
hans@947: For publishing the changes to the {\tt artifact-server}, it needs to be
hans@947: restarted.
tim@906:
hans@947: \subsection{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}
hans@947:
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:
hans@947: \paragraph*{Example}
hans@947: This example shows how to add a FIS and illustrates the effect on the
hans@947: artifact-server's output.
tim@916:
hans@947: First , the following {\tt artifact-factory} has to be added into the file
tim@941: {\tt conf/conf.xml} in section {\tt /artifact-database/artifact-factories}
hans@947: adding a new FIS called {\tt justanewfis} to the server:
tim@916:
tim@916: \begin{lstlisting}
hans@947:
tim@916: de.intevation.gnv.artifacts.GNVProductArtifactFactory
tim@916:
tim@916: \end{lstlisting}
tim@916:
hans@947: Restart the {\tt artifact-database} executing:
tim@916:
tim@920: \begin{lstlisting}
hans@947: /etc/init.d/artifact-server restart
tim@920: \end{lstlisting}
tim@916:
hans@947: Checking if the new FIS is served by the REST-Server
tim@916: calling the following command:
tim@916:
tim@920: \begin{lstlisting}
hans@947: curl http://localhost:8181/factories | xmllint --format - | grep fis_justanewfis
tim@920: \end{lstlisting}
tim@916:
hans@947: If the FIS was added, the new {\tt artifact-factory} will be found in the generated
hans@947: XML-output. Otherwise no XML-output will be shown.
tim@916:
hans@947: \subsection{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}
hans@947:
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:
hans@947: To prevent needless configuration-work, it is a useful way to clone an
hans@947: existing artifact handling the same kind of work.
tim@906:
tim@917:
hans@947: \paragraph*{Example}
hans@947: Now will an artifact to the FIS {\tt fis\_justanewfis}, will be configured.
tim@917:
hans@947: The following XML-fragment has to be added to the file
tim@941: {\tt conf/conf.xml} in section {\tt /artifact-database/artifacts}:
tim@917:
tim@917: \begin{lstlisting}
hans@947:
tim@917:
tim@917:
tim@917:
tim@917: \end{lstlisting}
tim@917:
hans@947: Restart the artifact-server
tim@917:
tim@919: \begin{lstlisting}
hans@947: /etc/init.d/artifact-server restart
tim@919: \end{lstlisting}
tim@917:
hans@947: Now it should be possible to choose the artifact.
tim@919:
hans@947: The listbox in the GUI would 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:
hans@947: \subsection{Adding/Removing Products to the Specific Artifact}
hans@947: Next step is, to configure the different products which the FIS should
hans@947: be able to provide. To do this it is necessary to copy the
hans@947: XML-fragments of the products into the XML-element {\tt products} of the
hans@947: previously integrated artifact.
hans@947:
tim@906: \begin{lstlisting}
hans@947:
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:
hans@947: In this XML-fragment the placeholders {\tt NEWFISNAME} have to be
hans@948: replaced. The source-id \texttt{VALUEOFSOURCEID} with the value for the new
hans@947: FIS as defined in the table {\tt MEDIAN.SOURCEINFO} needs to be added.
tim@906:
hans@947: \paragraph*{Example}
hans@947: Adding a product to the new FIS, choosing sourceid of an existing FIS
hans@947: (e.g 4 $\rightarrow$ Marnet).
tim@918:
hans@947: 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:
hans@947: Restart the artifact-server
tim@918:
tim@919: \begin{lstlisting}
hans@947: /etc/init.d/artifact-server restart
tim@919: \end{lstlisting}
tim@919:
hans@947: If
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:
hans@947: is called, the product {\tt timeSeries} should be available for the FIS {\tt justanewfis}.
tim@918:
hans@947: Now, it should be able to choose the product.
hans@947: This product including the definied outputformats should be available in
hans@947: the GUI.
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:
hans@947: All products are configured in separated files that will be included into the
tim@940: main configuration using Xlink-references.
tim@906:
hans@947: First step is to create a new file in the folder {\tt products} and in the
tim@941: sub-folder where the product belongs to ({\tt timeseries,verticalprofile,
tim@941: horizontalprofile,horizontal\-crosssection,layer,...})
tim@906:
hans@947: Then the new product can be referenced 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:
hans@947: \subsection{Adding an additional Product to a FIS}
hans@947: To add an additional product to a FIS the XML-fragment which
tim@940: represents the product to the artifact-configuration of the FIS in section
hans@947: {\tt /artifacts/artifact/products} needs to be added.
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:
hans@947: Please note that the placeholders have to be explained above.
