One purpose of PHOS16 was to offer complementary perspectives on openness as a core scientific value. Varying contemporary definitions of open science and their roles and limitations in academic value creation were covered by Benedikt Fecher’s talk on the open science schools of thought (“Publishing and the Limits of Openness”; see also Fecher and Friesike 2013). This talk was complemented by Caroline Bassett’s paper which considered the broader historical and philosophical context of open science, and its associated uncertainties and risks, in terms of the concept of expertise (“Enough of Experts? Publics, public knowledge, and expertise”).

The challenges for openness were considered on both structural and microsocial levels. Examples of structural challenges include technical and institutional aspects such as funding models, science policy and regulation, and communication technologies as well as social aspects such as gender bias and family upbringing, which can remarkably limit an individual’s chances of entering and succeeding in academia. An example of the latter is the fact that access to the scientific community has historically been largely restricted to men, as was showcased by Camilla Mork Rostvik in her talk on women and the Royal Society: "Too Ambitious’? The History of Women and Publishing at the Royal Society in the 20th and 21st century”. Sociological mechanisms, technological development, and market forces are closely related issues that have been central drivers for, as well as threats to, openness in research practices since the Enlightenment. Manuela Fernández Pinto addressed these issues in her talk entitled “Open Science closed for business?” Sociological perspectives to open science include thinking about epistemic cultures and “how we know what we know” (Cetina 1999). These issues, as well as social structures in general, were discussed by Werner Reichmann in his talk "Open Science, Epistemic Culture, and Social Structures".

One hotly debated set of issues at the conference included the analysis of the concept of socially relevant knowledge, the idea of co-production, and the tensions between expert knowledge and democratization of research (Koskinen 2016). Open research practices often seem to refer to transparent reporting, equal opportunity, open communication, and the various technical aspects of research rather than to democratisation of academic research. These issues were treated by Inkeri Koskinen in her talk on transdisciplinary research, titled “Commercialisation Threatening Openness in Transdisciplinary Research”.

Open science is also an active movement which is driven by an increasing number of scientists adopting, innovating, and promoting open practices to improve the quality of research, collaboration, and overall visibility of their research. There are also conscious endeavours towards explicit policy goals seeking to influence prevailing institutions: the various national campaigns to increase transparency in the current academic publishing model provide one topical example. These campaigns aim at redefining the relationship between the academic community on the one hand and commercial publishers on the other (a Finnish example of such a campaign is www.tiedonhinta.fi). Various forms of, and efforts at, democratisation constitute a crucial part of and a driving force behind the contemporary movement, including increased levels of participation, activist research, extra-academic collaboration, citizen science, or transdisciplinarity. For instance, data collection in ecology, biomedicine, and many other fields often relies on lay volunteers, and sharing research data with others is now making it possible for individuals to compare their genetic makeup or microbial fingerprints compare with others. An important related aspect is the question of authority and different kinds of expert knowledge as contrasted with citizen science. Caroline Bassett linked this question with what’s called post-truth or alt-fact politics. On the other hand, citizen science enterprises can help build trust in and give insights into scientific practice. In the future, we are likely to encounter increasingly interesting and at times difficult questions about citizens who do science on the one hand and scientists who are representing the view of citizens as opposed to institutional point of view on the other.

While there have been tensions between openness and profit-seeking, secretive, and often privateinterests, the transition into more and more open science is ongoing on all levels within the academic community and a number of publishers and commercial companies have identified rapidly emerging business opportunities. Public interest has a remarkable role in defining the rules and regulations within the scientific community, including the standards for openness. While societal impact does not equal financial impact, open science can also be profitable. Openness can increase the overall efficiency of research and dissemination thereof, thus bringing added value to the allocation of resources. Its value can be challenging to quantify, however, and adoption of open practices has concrete costs that need to be accounted for within academic research and funding communities. Open science is simultaneously driven by various parties and that its development is in part due to the tensions just enumerated rather than despite them.

Since the early modern period, scientific endeavour has been motivated by a desire for knowledge driven by ideas, not authorship, with the result that texts have often been anonymous. Opening medieval codices, one is struck by how often they are compilations of sources on one topic rather than assembled groups of works by one author. This creates significant challenges in assigning authorship and new technologies are providing new opportunities to study medieval scholarship, for instance by cross-linking and collaborative analysis of texts, over great distances and at an historically unprecedented scale. These new collaborative methods and ways of accessing sources are significantly changing the ways in which historical sources are contextualised and understood as well as highlighting their influence in the long term. The most recent developments in this field were covered by Jeffrey Witt in his talk referencing the work done at the Scholastic Commentaries and Texts Archive (“Texts as Networks: The Promise and Challenge of Publishing Humanities Texts as Open Data Networks”).

The concluding panel discussed among other things the fact that in addition to openness in academic processes having intrinsic value in itself, it also has an instrumental role in the advancing the generation, accumulation, and dissemination of knowledge which is central to the practical questionsof shaping research policies and funding models.

In many ways, open science is a very pragmatic concept that promotes access to scientific outputs to facilitate the process of knowledge generation. All this is facilitated by technological development, as was illustrated by Scott Chamberlain’s talk on contemporary Software and Best Practices to Facilitate Open Science.

Improved access to scientific research data, methods, publications as well as other outputs of scientific research will not only serve to increase transparency. It will also provide opportunities for further use, and innovative combinations, of ideas, information, and data. This is turn opens new avenues for creative thinking and scientific activity.

The recently proposed European Open Access Platform and the so-called diamond open access model have gained attention and provide one alternative that could replace the currentcommercial publishing system in the long term (see e.g. Fecher et al. 2017).

Modern technologies have opened up historically significant opportunities driving a culture shift inhow we share, collaborate, trust, and evaluate scientific work (Levin and Leonelli 2017, Laine et al. 2015). Making peer review, including review comments, and potentially even the identities of reviewers, open and attributable can improve the quality of reviews, help to avoid conflicts of interest, and facilitate collaboration (Aleksic et al. 2014). However, further research is needed to evaluate the relative merits or potential disadvantages of opening the various elements of the review process. These issues were discussed in Michael Markie’s talk on freeing peer review, “OPEN SESAME – Let’s Free Peer Review and the Sharing of Research”, and Samuli Ollila’s talk "Open Collaboration Method Developed in NMRlipids Project".

New technologies come with remarkable practical and social challenges such as the storage of massive data collections, the need for increasingly sophisticated algorithms, and the overall dependence on technology. Culture and norms do not always follow technical opportunities. While the digital revolution of recent decades has changed the way we communicate irreversibly, many popular features of the present open science movement, such as open data or electronic notebooks, are of concern to a very specific geographically, economically, and technically privileged set. We can therefore with good reason ask the following: on what grounds should we talk about the history of open science that extends beyond the digital era? These themes were discussed from a bird’s eye perspective by Koen Vermeir in his talk “Open Science: The Big Picture”.

Looking back at the historical and philosophical foundations of openness in the scientific process generally will be valuable for understanding, and also guiding, the ongoing transformation of the academic system into a more open way of doing science. One way to do this is to utilise established ethical frameworks as tools for the evaluation of and decision-making about open science (Mustajoki and Mustajoki 2017). The ethical aspects of open science research were addressed my Arto Mustajoki in his talk on fresh angles on the ethics of scientific research: “Open Data in the Framework of a New Approach to Research Ethics”.

We believe these kinds of well-founded and systematic approaches to open science can and should be interwoven also into discussions of open science and its role in research ethics and integrity. An example of how this might be done was provided by Katrien Maes’ talk on how European research institutions can be a force in making openness in science reality (“Europe Needs Ongoing Efforts to Promote Research Integrity – What LERU Universities Contribute to the Debate”).

The reasons for using cryptic alchemical notations in the 17th century have been transformed into new kinds of challenges associated with the complexity of modern information technologies. Despite this transformation, there are strong parallels between the different eras regarding issues of reproducibility, priority, scientific communication, funding, commercialization, and other aspects of doing science. These new forms of challenges contribute both to the modern reproducibility crisis and to the push towards more open science (Pinto 2015). Jennifer Rampling’s recent analysis of medieval and early modern science and medicine (Rampling 2013) explored the issues of how early experimenters dealt with problems of reproducibility. Using the historical example of alchemy, she demonstrated some ways in which this was done also in her engaging talk on “Reproducibility and the Language of Alchemy”.

The complex alchemical recipes that featured in Rampling’s talk were then sharply contrasted by Scott Chamberlain’s aforementioned talk on the latest modern practices of shared and reproducible software as well as Mikael Laakso’s talk on the latest research on exploring the ecosystems surrounding traditional scientific publishing and feasible open access (“Charting the Evolving Landscape between Paywalls and Sustainable Open Access: Practices, Problems, and Solutions”). The emergence and growth of modern open access publishing are making scientific literature available to the public at an unprecedented scale, although realised access to this literature is still limited by economical and social factors. It remains to be seen how the open science revolution will be able to shape societies in the future.
