This is the main website of the TRR379.

This website is not just a public-facing view on the consortium. It is specifically built to be the core component of the metadata concept of TRR379. It provides a collection of canonical definitions of entities essential for the function of TRR379. Such entities include

• projects of the TRR
• contributors to the TRR
• publication from the TRR membership
• site of the consortium
• …

Semantics

Any such entity has a dedicated page on the website, with a stable URL that serves as a URI for that entity. As such, these URLs can be used in any TRR379-related metadata to declare relationships to TRR379 entities, for example, the authorship of a publication, the origin project of a data release, etc.

The website is built with the static site generator Hugo. It capitalized on its taxonomy feature. Any page on the site is built from a metadata record. For Hugo, this metadata is presented in the form of a page’s front matter. However, these metadata may themselves be generated from the result of a database query.

Here is an example record for TRR379 spokesperson Ute Habel:

title: Ute Habel
projects:
- a02
- a04
- q01
- q04
sites:
- Aachen
- Juelich
roles:
- pi
- spokesperson
layout: contributor
params:
  orcid:  0000-0003-0703-7722
  name-title: Prof. Dr. rer. soc.
  affiliation: Department of Psychiatry, Psychotherapy and Psychosomatics, Faculty of Medicine, RWTH Aachen University
  sortkey: "Habel, Ute"

<additional content on the page's subject>

From this information, the page that identifies and describes Ute Habel as a spokesperson is generated. It also links and references her record on the respective pages for projects, sites, and roles she is associated with. Consequently, the URL https://www.trr379.de/contributors/ute-habel/ can serve as a URI for Ute Habel within the TRR379 metadata. Moreover, ute-habel is a unique identifier for her as a contributor to TRR379.

While other special-purpose identification systems exist (e.g., https://orcid.org for academics), this approach is automatically applicable to any concept and entity relevant to TRR379. Including roles, data acquisition methods, instruments, etc. The domain root trr379.de represents a unique namespace to define and reference any required entities. This enables a timely and unencumbered development of a metadata concept for TRR379, without hindering alignment with and mapping to more global efforts and initiatives.

Look

Structured metadata is rendered to an HTML website with Hugo using a template. This approach separates the information from its presentation.

The look of the website can be altered by adjusting the template, or switching to a different template entirely. This requires familiarity with Hugo and its templating mechanism.

At present, the congo template is used.

docs.trr379.de

https://docs.trr379.de (this site) is the main documentation source for the TRR379. It offers information on facilities and procedures.

hub.trr379.de

https://hub.trr379.de is the central (data) collaboration site of the consortium. It runs an enhanced variant of the Forgejo software that is designed for maximum interoperability with the RDM solution DataLad.

The main difference to the Gitlab solution – that is also employed by TRR379 for internal purposes – is the ability to also host arbitrarily large data on the same site. The integration with the git-annex software makes it ideal for the federated, multi-site nature of TRR379. The full software-stack is free and open source software, and can be deployed at any collaborating site with minimal effort. This aspect is essential for supporting the decentralized RDM approach of the TRR.

Any contributor can have an account on the central hub. Please contact Michael Hanke to get set up.

nb-query.trr379.de

https://nb-query.trr379.de hosts the central NeuroBagel query interface of the TRR379. With this solution, data availability can be queried dynamically, to faciliate data access requests.

NeuroBagel supports federated queries and is therefore ideally suited for the decentralized research data management approach of TRR379.

concepts.trr379.de

https://concepts.trr379.de hosts resources and documentation on the metadata models driving the research data management procedures of TRR379.

data.trr379.de

https://data.trr379.de hosts the data catalog of the TTR379. This site is currently work in progress, and will be published once the project has started to accumulate data.
