AWS Data Exchange vs Data Licensing Alliance

AWS Data Exchange is a marketplace for finding, subscribing to, and sharing data products. It has more than 3,500 products from over 300 providers, including over 1,000 free data products and custom data products. Offerings can be delivered as files, through APIs, or as Amazon Redshift, Amazon S3, and AWS Lake Formation data sets; Lake Formation is marked Preview. Data can be exported to S3 and analyzed with Athena or Redshift, or used with SageMaker, EMR, Glue, and Lake Formation. CloudWatch Events can retrieve new data-set revisions to S3 automatically. The service encrypts data in transit with SSL/TLS and at rest with server-side encryption, and CloudTrail integration supports API-call auditing. Providers can offer free or paid subscriptions lasting 1 to 36 months, with private offers allowing customized terms. Prices for paid products are set by providers, and subscribers may also incur standard S3 transfer charges and costs for AWS services used to store, process, or analyze data. Public Open Data on AWS products can be accessed with or without an AWS account.

Data Licensing Alliance is a marketplace for licensing STEM datasets for artificial intelligence and machine-learning work. Buyers search available data, while prediction technology suggests additional or alternative datasets. A buyer can license an entire dataset or a subset such as figures, paragraphs, or images, then set intended use, users, and duration in a clickwrap license. Data owners set prices, rights, permissions, and contractual limits. Delivery may use an API key, FTP transfer, or another owner-selected method. The marketplace offers machine-readable formats and standards; DLA’s consulting service lists JSON, FHIR, FSIR, and JATS conversions. Owners receive reporting on licensees, searches, views, licenses, and transactions. DLA states that owners retain raw-data ownership while buyers own derivative datasets or knowledge graphs. Sellers pay $100, capped at $1,000, plus transaction fees.
