We present a practical approach for provenance capturing in Data-Intensive workflow systems. It provides contextualisation by recording injected domain metadata with the provenance stream. It offers control over lineage precision, combining automation with specified adaptations. We address provenance tasks such as extraction of domain metadata, injection of custom annotations, accuracy and integration of records from multiple independent workflows running in distributed contexts. To allow such

Provenance Types handle domain contextualisation and allow developers to model lineage patterns by re-defining API methods, composing easy-to-use extensions. Provenance Configuration, instead, enables users of a Data-Intensive workflow execution o prepare it for provenance capture, by configuring the attribution of Provenance Types to components and by specifying grouping into semantic clusters. This enables better searches over the lineage records. Provenance Types and Provenance Configuration are demonstrated in a system being used by computational seismologists. It is based on an extended provenance model, S-PROV.
