This FME Desktop Package contains the Socrata Reader/Writer introduced with FME 2019.
The Socrata Reader/Writer in this package supersedes the Socrata DataSync Writer introduced in FME 2013.
Overview
Socrata makes it easy to share tabular data with collaborators or make data accessible to the public.
Socrata supports geometry in its columns. This plug-in exposes geometry as attributes with a geometric attribute type, and a value in Well-Known Text (WKT).
Reader Overview
The Socrata Reader uses the Socrata Open Data API (SODA) to download the dataset as a CSV, and then transform the rows to FME features. The results can be filtered by providing a WHERE clause in the Socrata Query Language (SoQL).
Dates and times are returned as-is from the API. The Socrata Reader does not convert them to FME date format.
Reader Dataset
The Reader Dataset is the URL for a Socrata Dataset. It must contain a valid Socrata Four-Four ID. Examples of valid dataset URLs include:
https://opendata.socrata.com/Demo/French-cheeses-dataset/m58b-pmus
https://opendata.socrata.com/api/views/m58b-pmus
Writer Overview
The Socrata Writer works by saving output features to a CSV file, which is then uploaded and transformed using the Socrata Publishing API. The Socrata Writer can create new datasets, and either replace or append to existing datasets.
The Socrata Publishing API performs a schema scan on the uploaded CSV to determine the appropriate column types. The Socrata Writer may submit a revised transformation to the server if the column types decided by the server do not agree with the attribute types set on the writer feature type schema. In the case of dates and times, the Socrata Writer defers to the formatting determined by the server-side schema scan.
The server may reject rows in the uploaded CSV. This typically occurs if the row’s data does not match the schema. The Socrata Writer will log the error count, and include a link to the CSV error report provided by the server.
Writer Dataset
The Writer Dataset is the URL for a Socrata Dataset.
- For append and replace operations, it must be the URL for an existing dataset.
- When creating a new Socrata Dataset, this field must either be empty or be a URL for only the host.
Examples of valid dataset URLs include:
https://opendata.socrata.com/ (for dataset creation)
https://opendata.socrata.com/Demo/French-cheeses-dataset/m58b-pmus
https://opendata.socrata.com/api/views/m58b-pmus
