IUCLID

The Data Uploader application is developed as a KNIME Analytics Platform plug-in comprising of several workflow nodes. Its aim is to allow easy data mapping and import of non-IUCLID data into IUCLID in a controlled way, supporting all IUCLID data sections.

The Data Uploader supports the transformation of data on chemicals to the IUCLID format. It is especially useful for conversion of legacy toxicity data into harmonised templates which can be stored in a IUCLID database. This tool can be used by owners of chemical databases who would like to share their information in an internationally recognised format. The application is developed as a KNIME Analytics Platform plug-in, comprising of several workflow nodes.

The main Data Uploader workflow consists of 6 tailor-made KNIME nodes:

• Connection to a IUCLID database
• Selection of relevant IUCLID documents and fields
• Mapping with an external data source
• Validation of the data against the IUCLID format
• Generation of IUCLID files (.i6z)
• Upload to IUCLID

The Data Uploader workflow with the Incremental update node supports a stepwise approach and other incremental update scenarios. With the stepwise approach the user is able to upload a set of simple entities, e.g. Reference Substance, Legal entity, Literature, that can be used later as references in SUBSTANCE or TEMPLATE documents. This reduces the complexity of the KNIME workflows to transform the data and improves the overall user experience.

Other incremental update scenarios include creating an entity (SUBSTANCE, TEMPLATE…), creating documents (ENDPOINT_STUDY_RECORD, FLEXIBLE_RECORD…), editing fields within an entity/document and deleting entities/documents.
