Introduction: The Minimum Information About BIobank data Sharing (MIABIS) was initiated in 2012. MIABIS aims to create a common biobank terminology to facilitate data sharing in biobanks and sample collections. The MIABIS Core terminology consists of three components describing biobanks, sample collections, and studies, in which information on samples and sample donors is provided at aggregated form. However, there is also a need to describe samples and sample donors at an individual level to allow more elaborate queries on available biobank samples and data. Therefore the MIABIS terminology has now been extended with components describing samples and sample donors at an individual level.Materials and Methods: The components were defined according to specific scope and use cases by a large group of experts, and through several cycles of reviews, according to the new MIABIS governance model of BBMRI-ERIC (Biobanking and Biomolecular Resources Research Infrastructure-European Research Infrastructure Consortium). The guiding principles applied in developing these components included the following terms: model should consider only samples of human origin, model should be applicable to all types of samples and all sample donors, and model should describe the current status of samples stored in a given biobank.Results: A minimal set of standard attributes for defining samples and sample donors is presented here. We added an "event" component to describe attributes that are not directly describing samples or sample donors but are tightly related to them. To better utilize the generic data model, we suggest a procedure by which interoperability can be promoted, using specific MIABIS profiles.Discussion: The MIABIS sample and donor component extensions and the new generic data model complement the existing MIABIS Core 2.0 components, and substantially increase the potential usability of this terminology for better describing biobank samples and sample donors. They also support the use of individual level data about samples and sample donors to obtain accurate and detailed biobank availability queries.

The article traces the genealogy of the Minimum Information About Biobank Data Sharing model, created in the European Biobanking and Biomolecular Resources Research Infrastructure to facilitate collaboration among biobanks and to foster the exchange of biological samples and data. This information model is aimed at the identification of biobanks; unification of databases; and objectification of the information, samples, and related studies – to create a completely new ‘bio-object infrastructure’ within the EU. The paper discusses key challenges in creating a ‘universal’ information model of such a kind, the most important technical translations of European research policy needed for a standardised model for biobank information, and how this model creates new bio-objects. The author claims that this amounts to redefinition of biobanks and technical governance over virtually bio-objectified European populations. It is argued here that old governance models based on the nation-state need radical reconsideration so that we are prepared for a new and changing situation wherein bodies of information that lack organs flow from one database to another with a click of a mouse.
