The BMDV open data portal mCLOUD offers a Export interface (REST-API) via the data as RDF according to the DCAT-AP.de specification or can be exported as CSV. Export as DCAT-AP.de in RDF/XML: Basic path: https://mcloud.de/export/datasets Export as CSV: Basic path: https://mcloud.de/export/csv/datasets Parameters: The parameters in the requests are based on the parameters in the portal for a remote search (URL). At the end of a hit page in the portal, the export is always offered. So one possibility is to search the portal as normal and then copy the export URL at the end of a page. Individual data set A single data set can be retrieved by appending the UUID. E.g. https://mcloud.de/export/datasets/922e436b- 2f0d-42d7-b3f4-528debab8b87 This export is directly available in the mCLOUD in the data record as a "link to the metadata". Predefined filters: All data sets that have been added in the last 24 hours: filter=newdatasets https://mcloud.de/export/datasets?filter=newdatasets All datasets that were changed in the last 24 hours (also includes newly added sets): filter=modifieddatasets https://mcloud.de/export/datasets?filter=modifieddatasets Paging (default): pageSize=10 (number of sentences on one page) page=1 (display first page) https://mcloud.de/export/datasets?page=1&pageSize=10 Im DCAT-AP.de export always includes navigation information at the beginning: itemsPerPage (= pageSize parameter) totalItems (total number) firstPage (= first page for page parameter) lastPage (= last page for page parameter) Search term: query=Vehicle https://mcloud.de/export/ datasets?query=Vehicle Search facet: aggs=... The facet is then specified exactly as in the portal request. Please note the coding: format%3ACSV = type of access "CSV" categories%3Aroads = category "road" format%3ACSV%40%40categories%3Aroads = type of access "CSV" AND category "road" Together: aggs=format%3ACSV %40%40categories%3Aroads https ://mcloud.de/export/datasets?aggs=format%3ACSV%40%40categories%3Aroads Here is the search in the portal, you can use this as a guide: https://mcloud .de/web/guest/suche/-/results/filter/auto/format%3ACSV%40%40categories%3Aroads/0 At the end of the page there is also the link (as RDF): https://mcloud.de/export/datasets?page=1&pageSize=1147&sortOrder=desc&sortField=latest&aggs=format%3ACSV%40%40categories%3Aroads Sort field: No entry sorted by ID of the datasets sortField=relevance (relevance) sortField=latest (actuality) Sort order: sortOrder=asc (ascending, default) sortOrder=desc (descending)
