ADA in Brief

• The Social Science Data Archive (now ADA) was set up in 1981, housed in the Research School of Social Sciences, with a mission to collect and preserve Australian social science data on behalf of the social science research community

• The Archive holds over 5000 datasets from around 1500 studies, including national election studies; public opinion polls; social attitudes surveys, censuses, aggregate statistics, administrative data and many other sources.

• Data holdings are sourced from academic, government and private sectors.

So what is a data archive?

• ‘A “trusted system” that provides... an accessible and comprehensive service empowering researchers to locate, request, retrieve and use data resources in a simple, seamless and cost effective way, while at the same time protecting the privacy, confidentiality and intellectual property rights of those involved.’

Managing and Depositing Data: ADA and DDI

Data deposit: ADAPT

Archival processing

Manual system with some automation tools1. Deposit:

– Review of ADAPT submission– Storage via ADAPT to file store

2. Data processing:– File format conversion (usually to SPSS for processing)– Privacy/confidentiality review– Data cleaning (in consultation with depositor)

3. Metadata processing:– DDI-C metadata creation in Nesstar Publisher

4. Publishing:– Archival storage and access format creation– Data publication to Nesstar server– Metadata publication to Nesstar and ADA CMS

Future directions

Future trends

• Mandated rather than recommended data archiving– How do we scale?– Looking at self-deposit systems

• Open access to data as the default – Government: PM&C Open Data Policy, data.gov(.au/.uk)– Research: Horizon2020, ESRC, NSF, ARC/NHMRC??

• Broader range of data types available– Qualitative data: YES– Social media data:

• Raw feed (firehose): NO • Processed data: ??? (how to support access)

– Administrative data: ???• Broader range of users of that data

– Different disciplines: health, environment, comp. sci.– Different users: public/media/government– Different geographies: internationally

Core needs for social science data

• Collection• Preservation• Integration• Analysis• Dissemination

ADA trusted digital repository project

• Funded by ANDS 2016-17• Aims:

– Completion of the Data Seal of Approval self-assessment and certification process

• http://www.datasealofapproval.org/en/ • 16 requirements: • Assessment on 0-4 scale:• All requirements must be at least a 1

– Implemention of improvements to ADA systems and procedures to improve certification assessment

– Review of the DSA certification process and criteria to assess suitability for the Australian research data environment

DSA requirements

• “Fundamental to the following guidelines are five criteria, that together determine whether or not the digital research data may be qualified as sustainably archived:– The research data can be found on the Internet.– The research data are accessible, while taking into account

relevant legislation with regard to personal information and intellectual property of the data.

– The research data are available in a usable format.– The research data are reliable.– The research data can be referred to.”

• http://www.datasealofapproval.org/media/filer_public/2013/09/27/dsa-booklet_1_june2010.pdf

The guidelines

• “The associated guidelines relate to the implementation of these criteria and focus on three stakeholders: the data producer, the data repository and the data consumer.1. The data producer is responsible for the quality of the digital research

data.2. The data repository is responsible for the quality of storage and

availability of the data and data management.3. The data consumer is responsible for the quality of use of the digital

research data.”– http://www.datasealofapproval.org/media/filer_public/2013/09/27/dsa-b

Repositories and archives project

• With UNSW Library (Maude Frances)• Exploring mechanisms for deposit and preservation

of data through repository to the data archive• Questions we are exploring:

– Where should we deposit the data?– Who should store the data?– What metadata should we collect?– Who should manage the metadata?– How to transfer content (data and metadata) between

repository and archive?– How to determine the “source of truth”? (e.g. who should

mint the DOI?)

ADA Dataverse

• Redevelopment of our database and website infrastructure– New website– New data catalogue

• New functionality:– Self-deposit of data– Open data access– API access (both for deposit and access, e.g. through R)– Shibboleth authentication

• Currently in early testing– For completion in 2017 (probably Q3)

• Functionality intended to support additional DSA requirements

Data documentation standards

DDI-Codebook

• Two flavours of DDI – Codebook and Lifecycle• Focus on DDI-C, four sections:

1. Document description: characteristics of the DDI XML document itself

2. Study description: characteristics of the Study (project) that the DDI is describing (including Related Materials: documents associated with the project, such as questionnaires, codebooks, etc.)

3. File description: characteristics of the physical data files4. Variable description: characteristics of the variables in the

data file

Dublin Core

• Type• Format• Identifier• Source• Language• Relation• Coverage• Rights

• Title• Creator• Subject• Description• Publisher• Contributor• Date

DCAT (W3C)

DCAT standard is relatively simple, and includes four basic objects:• Dataset: “a collection of data, published or curated by a

single agent, and available for access or download in one or more formats”

• Data catalog(ue): “ a curated collection of metadata about datasets”

• Catalog(ue) record: “a record in a data catalog, describing a single dataset”

• Distribution: “represents a specific available form of a dataset”

• Key object for SRC is the Dataset– others are distribution-related

ADA systems architecture

Approach

• Core archive website: – http://www.ada.edu.au

• Sub-archives focussed on specialised thematic or methodological areas- eg. http://www.ada.edu.au/indigenous/home

• “Add-on” systems for complex analysis or visualisation tasks:– Nesstar– GIS: http://gis-test.ada.edu.au– Longitudinal visualisation: Panemalia– Historical census data: http://hccda.ada.edu.au

Data sharing policies in Australia

Policy trends in data access

• Mandated rather than recommended data archiving• Open access to data as the default (NSF, Office of

the President, data.gov(.au,.uk))• Broader range of data types available• Broader range of users of that data

Policy drivers

• Funders: Return on investment:– Government data: Treasury, PM&C– Research data: ARC/NHMRC, Horizon 2020

• Journal publishers: Reputation:– Open access journals (e.g. PLOS One) and – For-profit publishers (e.g. Nature, Science, Elsevier)

concerned about loss of credibility from fraudulent research• Learned societies and disciplines: Good science

AND reputation: – American Political Science Association: DART initiative– American Economic Association:

Government data

• Australia: Australian Government Public Data Policy Statement– The Australian Government commits to optimise the use and

reuse of public data; to release non-sensitive data as open by default; and to collaborate with the private and research sectors to extend the value of public data for the benefit of the Australian public.

– Public data includes all data collected by government entities for any purposes including; government administration, research or service delivery.

– Non-sensitive data is anonymised data that does not identify an individual or breach privacy or security requirements.

Research data

• Australian Code for the Responsible Conduct of Research

• https://www.nhmrc.gov.au/guidelines-publications/r39 (Joint ARC/NHMRC publication)

• Section 2: Management of research data and primary materials

• Then provides related links to ethics statements and similar

ACRCR Section 2: Responsibilities of Institutions

Section 2.1.1: In general, the minimum recommended period for retention of research data is 5 years from the date of publication. However, in any particular case, the period for which data should be retained should be determined by the specific type of research. For example:• for short-term research projects that are for assessment purposes

only, such as research projects completed by students, retaining research data for 12 months after the completion of the project may be sufficient

• for most clinical trials, retaining research data for 15 years or more may be necessary

• for areas such as gene therapy, research data must be retained permanently (eg patient records)

• if the work has community or heritage value, research data should be kept permanently at this stage, preferably within a national collection.

ARC statement

"Researchers and institutions have an obligation to care for and maintain research data in accordance with the Australian Code for the Responsible Conduct of Research (2007). The ARC considers data management planning an important part of the responsible conduct of research and strongly encourages the depositing of data arising from a Project in an appropriate publicly accessible subject and/or institutional repository"

ANDS suggest three questions

1. Where will your research data be stored at completion of the project?

2. What access will you provide to the data set on completion of the project?

3. How will you enable others to reuse your research data?

Horizon 2020

• http://ec.europa.eu/research/participants/docs/h2020-funding-guide/cross-cutting-issues/open-access-data-management/open-access_en.htm

• (All grants): Develop a data management plan (DMP) within 6 months of commencement of project

• Pilot program (2014-17):– Deposit research data described in DMP, preferably in a

research data repository– As far as possible, projects must then take measures to

enable third parties to access, mine, exploit, reproduce and disseminate (free of charge for any user) this research data.

– Guidelines recommend FAIR principles
