1 Nikos Manolis Agro-Know Technologies Tutorial on data aggregation and accessing datasets

2 Slide 2 of 63 There is a lot of data

3 Slide 3 of 63 Need for data aggregation and harmonization

4 Slide 4 of 63 Objectives This presentation aims to provide information on:  How to use a service for aggregating datasets  How to get already processed datasets  How to search processed datasets with a search API Educational – GLN API (21008 res) Bibliographic – ABN API (451602 res)

5 Slide 5 of 63 The agDataHarvester service Implements the OAI-PMH protocol to harvest metadata records from open data providers – REST-based API – Harvested dataset available through HTTP

6 Slide 6 of 63 agDataHarvester parameters { "document_type": "harvesting_target", "harvesting_target": { " name ":"Repository name", " description ":”Short Repository Description", " url ":"OAI-PMH target URL", " type ":"metadata format prefix", " frequency ":hours }

7 Slide 7 of 63 param.json { "document_type": "harvesting_target", "harvesting_target": { "name":"Indian Academy of Science", "description":"Indian Academy of Science", "url":"http://repository.ias.ac.in/cgi/oai2","http://repository.ias.ac.in/cgi/oai2 "type":"mets", "frequency":24 } curl -X POST -d@INDUS.json http://'demo001':aginfra@agro.ipb. ac.rs/agcouchdb curl -X POST -d@ param.json tp://'demo001':aginfra@agro.ipb.ac.rs/agcouchdb { "ok": true, "id": " 5c56a3fa18fa21d2a85fd63cc9eb78ac ", "rev": "1- 19ef1210376df8f1695a32b53ecb963a" }

8 Slide 8 of 63 Get details on the dataset http://agro.ipb.ac.rs/agcouchdb/_design/datasets/_list/search/list?dataset.process_parameter_id= 5c56a3fa18fa21d2a85fd63cc9eb78ac

9 Slide 9 of 63 Get details on the dataset http://agro.ipb.ac.rs/agcouchdb/_design/datasets/_view/list_by_process?key=agdataharvester {" id ": " 6796259b52d79e4797e210c06e6a0aee ", "key": "6796259b52d79e4797e210c06e6a0aee", "value": { "_id": "6796259b52d79e4797e210c06e6a0aee", "_rev": "1-d55d7bc90d26db64dae328c9328e4e4a", "document_type": "harvesting_target", "harvesting_target": { "name": “ WorldBank ", "description": "The World Bank - Open Knowledge Repository", "url": ""https://openknowledge.worldbank.org/oai/request", "type": “mets", "frequency": 24 }, "document_publisher": { "address": "83.212.96.169", "author": "demo001", "utc_datetime": "Wed Dec 11 11:58:45 2013", "utc_timestamp": 1386763125 }

10 Slide 10 of 63 The agWorkflow service http://agro.ipb.ac.rs/agcouchdb/_design/datasets/_list/search/list? dataset.process=agworkflow&dataset.type=oai_lom&dataset.accuracy=true I want all datasets with educational resources processed by the agINFRA powered aggregation workflow ! http://agro.ipb.ac.rs/agcouchdb/_design/datasets/_list/search/list? dataset.process=agworkflow&dataset.type=oai_agris&dataset.accuracy=true I want all datasets with bibliographic resources processed by the agINFRA powered aggregation workflow !

11 Slide 11 of 63 Is there a way to search on available datasets ?

12 Slide 12 of 63 Search API REST-based queries over harmonized information (result of metadata processing) Two data models supported – akif: describing educational resources for agriculture, http://54.228.180.124:8080/search-api/v1/akif/?q=* – agrif: describing bibliographic resources for agriculture (mainly from FAO’s data), http://212.189.145.241:8080/search-api/v1/agrif/?q=*

13 Slide 13 of 63 Search options Simple search http://BASE_URL/search-api/v1/akif/?q=tomato Searching within specific fields http://BASE_URL/search- api/v1/akif/?languageBlocks.en.description=tomato Temporal http://BASE_URL/search-api/v1/akif/?creationDate=2013-04-16 Fetching specific items http://BASE_URL/search-api/v1/akif/COLLECTION/20296

14 Slide 14 of 63 Managing results Sorting results e.g ?q=*&sort_by=creationDate&sort_order=desc Facets e.g ?facets=set&facet_size=3 Pagination e.g ?q=sea&page_size=25&page=3 Full Documentation : 54.228.180.124:8080/search-api/
