Kustvakt is a user and policy management component for KorAP (Diewald et al., 2016). It manages user access to resources (i.e. corpus data) that is typically bound with some licensing schemes. The licensing schemes of the IDS resources provided through KorAP (DeReKo) are very complex involving the access location and purposes (Kupietz & Lüngen, 2014). To manage user access to resources, Kustvakt performs query rewriting with document restrictions (Bański et al., 2014).
Kustvakt acts as a middleware in KorAP binding other components, such as Koral a query serializer and Krill a search component, together. As KorAP's API provider, it provides services, e.g. searching and retrieving annotation data of a match/hit, that can be used by a client, e.g. Kalamar (a KorAP web user interface) and KorapSRU (the CLARIN FCS endpoint for KorAP).
Versions
Kustvakt lite version
provides basic search and match info services without user and policy management.
Kustvakt full version
provides user and policy management and extended services (e.g. resource and annotation services) in addition to the basic services. This version requires a database (Sqlite is provided) and an LDAP system for user authentication.
Web-services
Web-services including their usage examples are described in the wiki.
Setup
Prerequisites: Jdk 1.8, Git, Maven 3
Clone the latest version of Kustvakt
Since Kustvakt requires Krill and Koral, please install Krill and Koral in your maven local repository. Adjust the versions of Krill and Koral in Kustvakt/core/pom.xml according to the versions in Koral/pom.xml and Krill/pom.xml.
Install Kustvakt-core in your maven local repository
Package Kustvakt full version
The jar file is located in the target/ folder.
Package Kustvakt lite version
The jar file is located in the target/ folder.
If there are errors regarding tests, please skip them.
Customizing Kustvakt configuration
Copy the default Kustvakt configuration file (e.g. full/src/main/resources/kustvakt.conf or lite/src/main/resources/kustvakt-lite.conf), to the same folder as the Kustvakt jar files (/target). Please do not change the name of the configuration file.
Setting Index Directory
Set krill.indexDir in the configuration file to the location of your Krill index (relative path to the jar). In Kustvakt root directory, there is a sample index, e.g.
Setting LDAP
Set the location of the LDAP configuration file for Kustvakt full version. The file should contain an admin password to access an LDAP system. Without LDAP, user authentication functions and services cannot be used. Authentication mechanism can be extended by implementing other authentication methods e.g. using a database.
ldap.config = path-to-ldap-password
Setting BasicAuthentication for Testing
For testing, you can use/activate BasicAuthentication, see Spring XML configuration file for testing at /full/src/test/resources/test-config.xml. BasicAuthentication uses a dummy UserDao allowing all users to be authenticated users. You can implement UserDao by connecting it to a user table in a database and checking username and password for authentication.
<bean id="basic_auth" class="de.ids_mannheim.korap.authentication.BasicAuthentication" /> <util:list id="kustvakt_authproviders" value-type="de.ids_mannheim.korap.interfaces.AuthenticationIface"> <ref bean="basic_auth" /> ... </util:list>
Optional Custom Configuration
Changing Kustvakt Server Port and Host
Server.port = 8089 Server.host = localhost
Changing Kustvakt Service Base URL
The default base URL is
kustvakt.base.url=/kustvakt/api/*
Setting Default Layers
The values of the following properties are foundries.
default.layer.partOfSpeech = tt default.layer.lemma = tt default.layer.orthography = opennlp default.layer.dependency = mate default.layer.constituent = corenlp
Running Kustvakt Server
Requires kustvakt.conf or kustvakt-lite.conf in the same folder as the jar file. Otherwise assuming sample-index located in the parent directory of the jar file.
Kustvakt full version requires an LDAP configuration file containing an admin password to access an LDAP system. You can still run Kustvakt full version without an LDAP system, but user authentication functions and services cannot be used. Only services for guest/demo user would be available.
Futher Setup
Advanced setup including database and mailing setting are described in the wiki.
