Purpose Place-based foodstuffs have gained salience in markets worldwide and geographical indication (GI) products are prominent examples. The purpose of this paper is to focus on the governance (formal and informal institutions) of the European and Japanese GI schemes, discuss the variety of procedures of implementing the features of the governance system (inclusion and exclusion of actors) for six GI cases and reflect on future GI governance. Design/methodology/approach The criteria for assessing the six cases were descriptive and analytical and the information and data come from official documents, literature (scientific and “grey”), interviews, observations and personal communications with key-informants of the GI systems. Three of the cases are categorized as “failures” and are included to provide more insights on the diverse dynamics of GI systems. Findings Registration of GIs seems to be a process rather than a single step, requesting coordination and consensus and an interplay between internal and external actors. “Success” and “failure” are relative and related to self-governance processes and the openness of the social system of the GI to establish transparency on inclusion and exclusion. GI systems require constant management and re-definition of production quality or geographical boundaries to adapt to market, climate or technological change. Originality/value The paper introduces GI systems categorized as “failures” (either products that did not register as GIs in the end or did register but failed to keep the registration) which provides more insights on how to design and manage complex GI systems.

Flexible epoxy waveguide Bragg gratings are fabricated on a low-modulus TPX™ polymethylpentene polyolefin substrate for an easy to manufacture and low-cost optomechanical sensor pad providing exceedingly multipurpose application potentials. Rectangular EpoCore negative resist strip waveguides are formed employing standard UV mask lithography. Highly persistent Bragg gratings are inscribed directly into the channel waveguides by permanently modifying the local refractive indices through a well-defined KrF excimer laser irradiated +1/-1 order phase mask. The reproducible and vastly versatile sensing capabilities of this easy-to-apply optomechanical sensor pad are demonstrated in the form of an optical pickup for acoustic instruments, a broadband optical accelerometer, and a biomedical vital sign sensor monitoring both respiration and pulse at the same time.
