1 Open Structures for Agricultural Knowledge Management VDI-Expertenforum "Networking for Communication and Automation in Agricultural Engineering" Dr. Ansgar Bernardi DFKI GmbH, Kaiserslautern VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium

2 Integration of location-based data is the key to Knowledge Management in agriculture VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 2

3 Multiple participants will profit from efficient knowledge exchange Public geo data are a valuable basis for location-specific services Mobile access to data, knowledge sources, and services enable effective support on site The combination of public and private actors facilitates comprising and efficient services e.g. improved consulting combining public data and private services e.g. better data by exploiting individual sensor data VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 3

4 Example: Geodata and consulting know-how support operative activities Geo Katalog Data provision Location-based Decision Assistance Competence Center Biomass Planer Logistics Planer Feedback operational Production Management regional Ressource Management VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 4

5 Example: Feedback improves the data & knowledge Geo Katalog Data Provision Location-based Decision Assistance Competence Center Biomass Planer Logistics Planer Feedback operational Production Management Feedback regional Ressource Management VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 5

6 Example: Yield prognosis based on combination of data Rainfall Map Yield Prognosis Region Intermediate result BYM Table Soil quality Filter Diagram Field Data Online Rheinland-Pfalz (FLOrlp) Soil information Biomass Yield Models (BYM) * Zentralstelle der Länder für EDV-gestützte Entscheidungshilfen und Programme im Pflanzenschutz VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 6

7 Interactive Presentation of the calculated predictions Excel & Google Earth Ecological or conventional? Alternative rainfall assumptions Yield per field Yield per subfield VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 7

8 Digital soil quality maps provided by state government allow farmers to get an overview about the quality of their fields 40 The available maps give values for soil quality VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 8

9 Agricultural engineering provides relevant location-based data Recording of location, crop, humidity, and fuel consumption Humidity Sensor Melt Flow Sensor VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 9

10 Location-based recording of crop data leads to an up-date of soil quality maps Recorded on Average Value 12,23 t/ha Try Solids 100,40 t Humidity 73,55 % CROP (t/ha) from to HISTOGRAM VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 10

11 An open communication infrastructure is basis for all participants VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 11

12 igreen develops a communication platform for the exchange of data, knowledge,and services Semantic Technology: Easy understanding of shared data, due to explicit information about meaning and data format Easily extensible at any time Service Orientation: Flexible orchestration of multiple components Manufacturer-independent exchange Combination of public and private sources for data and knowledge VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 12

13 The Challenge: Flexible Data Handling Before talking about sensor data, provide me with a flexible solution for storing and managing such data LU Marx Goal: Universal data management for individual participants Flexible storage, including new attributes/values Allows to easily publish data Open for extensions (as data might become valuable in the future) Browsing in collected information Interfaces to sources and users Requirement: Individual ownership & control of data Local storage with controlled exchange in P2P networks VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 13

14 igreen relies on Semantic Technology Approach: Semantics of data is made accessible for the computer Attribute Formally defined vocabulary Concept, Relation Can be extended at any time Value Formally specified value ranges Can be extended at any time Ontology Applications (Programms) can look up Character and semantics of data at runtime VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 14

15 Don t try to standardize the data, but enable flexible sharing & uptake! Standards are useful and efficient, but standard creation is cumbersome Look at the flexibility & power of Web 2.0 and Linked Data! Approach: Enable to handle diversity! Not one standard data model but specify which data model YOU use Promise: Easy Mashup of data and web services VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 15

16 Separation of concerns results in Win-Win-situation Data owner: Make data available! (Electronically, with easy-to-use tools) Acess control, privacy, trust Service provider: Care for understanding available data Possible due to the semantic technology basis VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 16

17 igreen-vision: Services initiate the Data transfer Order, Access rights igreen Online Box Query Data Result Data owners make data available online Services issue queries and obtain the necessary data Crucial: Shared vocabulary / Ontology! VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 17

18 igreen Infrastructure make it easy to share data! Adressing of data sources & services DNS IP-NameServer, Web service registry Transmit requests, results, data http/rest RDF data format Make vocabulary explicit FAO AgroVoc, AgroXML -> AgroRDF Vocabulary server Individual extensions possible Translation by individuall converters (supported by generation workbench) Authentication Single-Sign-On in dedicated domains Make data available OnlineBox as reference implementation Integration with OGC-compliant geo data infrastructure VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 18

19 Communication with agricultural machines relies on ISOXML Operational data Sensor data Tasks, Application maps ISOBUS / ISOXML Machine Connector VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 19

20 Mobile Devices facilitate human-centered information access! Example: Prototype of a mobile documentation assistant, using Samsung Galaxy Personal access to data and services Flexible, rapid technological progress, high personal acceptance Development is ongoing Can we use Smartphones et al. as universal information assistant in direct connection to machines and sensors? VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 20

21 Service orientation asks for understanding the chain of interconnected, atomic operations Example: Order transmission support for contractors Farmer Geoformular Order including geo information (isoxml, GML) Contractor Machine instruction (isoxml) Equipment Geoeditor Field Geometry (GML, Shape,?) Driver Maps, InVeKoS-Data Public Geo data Public Geo data VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 21

22 igreen relies on available standards, whenever possible Geo data: GML Attributes/Values: RDF Vocabulary: AgroXML, FAO Concept server Processes, temporal dependencies, discourse: ebxml, CIDX Services: Web Service Technologie, SOA principles Machine- and sensor data: ISOBUS VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 22

23 igreen realizes an infrastucture for location-based services igreen delivers (via Web Services) Geo data provided by state governments Location-specific consultation Access to e-business data of suppliers and producers igreen Infrastructure Open, independent communication network Open interfaces, main software components open source Exemplary clients for mobile application mobile phone extended terminal VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 23

24 igreen results are basis for new and individual applications igreen documents Scenarios, processes, interfaces Who communicates? Why? Using which tools? igreen SDK Software libraries, universal and fundamental components as open source Enable programmers to effectively use the infrastructure igreen pilot applications and examples Demonstrate the new possibilities in actual and realistic examples VDI Expertenforum, Kaiserslautern, DFKI & igreen Consortium 24
