2. Right click on your PROJECT -> Export -> WAR

VM management

iptables prerouting was necessary to resolve ffma domain name

Deployment

{domain-name}/manager.html -> possible upload new WAR file for preservation-riskmanager.war or directly using e.g. WinScp /usr/local/tomcat/webapps/preservation-riskmanagement.war

Mongo start: run_mongo.sh -> install/mogodb_linux/bin

rm mongod.lock

Tomcat start: etc/init.d/tomcat stop/start

see /usr/local/tomcat/logs e.g. cat tail catalina.out Tomcat users are defined in server.xml -> tomcat.users.xml -> pwd user

Rest API

http://localhost:8983/ffma/component http://localhost:8983/ffma/services/preservation-riskmanagement http://{domain-name}/preservation-riskmanagement/ http://{domain-name}/common/rest/collection/list

a. http://{domain-name}/preservation-riskmanagement/rest/loddataanalysis/storeallextensions/AIT/true/true (As a response you will get created collections names like: AitFileFormat;LODFormat;LODSoftware;DipFormatId;DipSoftwareId;LODVendor;DipVendorId;)

b. http://{domain-name}/preservation-riskmanagement/rest/loddataanalysis/storeallextensions/Pronom/true/true (Response: PronomFileFormat;LODSoftware;DipFormatId;DipSoftwareId;)

c. http://{domain-name}/preservation-riskmanagement/rest/loddataanalysis/storeallextensions/Freebase/true/true (Response: FreebaseFileFormat;LODFormat;LODSoftware;DipFormatId;DipSoftwareId;LODVendor;DipVendorId;)

d. http://{domain-name}/preservation-riskmanagement/rest/loddataanalysis/storeallextensions/DBPedia/true/true (Response: LODFormat;LODSoftware;DipFormatId;DipSoftwareId;LODVendor;DipVendorId;)

Sample aggregation results (after loading data the following collections were created in mongodb):

AitFileFormat (14) DBPediaFileFormat (106) DipFormatId (576) DipSoftwareId (169) DipVendorId (18) FreebaseFileFormat (77) LODFormat (45) LODSoftware (317) LODVendor (19) PronomFileFormat (977)

CollectionAnalysisReport MetadataAnalysisResult

Check resulting collections existence using service http://{domain-name}/preservation-riskmanagement/rest/loddataanalysis/checkdataexist. As a response you should get a list of stored collections like (PronomFileFormat;DBPediaFileFormat;FreebaseFileFormat;LODFormat;LODSoftware;LODVendor;DipFormatId;DipSoftwareId;DipVendorId;).
