Release of nodegoat 7.3

CORE Admin

The release of nodegoat 7.3 comes with a set of new features that have been developed in collaboration with various projects and institutes.

Repertorium Academicum Germanicum: Vague and Complex Dates

The Repertorium Academicum Germanicum (RAG) at the University of Bern has commissioned a major overhaul of the nodegoat dating functionality. With this development process, the core of nodegoat's date handling processes have been rewritten to account for date statements that are uncertain/cyclical/relational. These statements can be expressed using 'ChronoJSON' notation, to allow for a clean and understandable description of complex date statement. We used the EDTF format as a starting point for this development process, but had to conclude that this format was not equipped to make relational date statements or include custom periodisations (like 'Sommersemester').

With these new features nodegoat users can now make statements like 'letter X was sent two months after letter Y and two months before letter Z', or 'Person A graduated on one day two years before 1498 and two years after 1498'.

These features are completely integrated into all nodegoat's functionalities. This means that you can create complex filters that use relational or vague date statements, include these levels of vagueness in your visualisation, and make selections of data based on vague dates to perform network analytical calculations.[....]

Data Publication by the MapModern Project

CORE Admin

The MapModern project at the Universitat Oberta de Catalunya (UOC) which focuses on cross-border literary networks and cultural mediators in the hispanic world between 1908 and 1939, has recently published a dataset on translations and reviews in hispanic modernist journals. This dataset has been created in their nodegoat database and currently includes all translations or reviews from La Revista (Barcelona) from 1915 to 1936; the second period of Proa (Buenos Aires) from 1924 to 1926, and Sur (Buenos Aires) from 1931 to 1939. More data from Iberoamerican journals will be added in the future.

Laura Fólica and Ventsislav Ikoff have collected the data, Diana Roig Sanz is the PI of this project. With the help of the staff of the UOC library, the dataset has been made Dublin Core compliant. The dataset can be downloaded from the data repository of the UOC: http://hdl.handle.net/10609/86485, or from the EUDAT Collaborative Data Infrastructure which has assigned the dataset with a DOI: 10.23728/b2share.eb5c468d3dc3401c8b2fb4605d868a00. The suggested citation is: Translations and Reviews in Iberoamerican Modernist Periodicals (dataset) by Fólica, Laura; Ikoff, Ventsislav; Roig Sanz, Diana; Dec 12, 2018.[....]

nodegoat Products

Since nodegoat's conception in 2011 by LAB1100, in collaboration with Joep Leerssen of the University of Amsterdam, our web-based research environment is used in various configurations by individual scholars as well as by large scale collaborative research projects.

The first project that started to use nodegoat was the Study Platform on Interlocking Nationalisms for their Encyclopedia of Romantic Nationalism in Europe in 2011. Since then it has been used by over twenty institutional projects and we have provided over a thousand individual scholars with access to a free personal research environment on nodegoat.net. The institutional projects are hosted on a server of the institute, and are offered in combination with training, workshops, and support. The individual accounts are hosted on our own server, located in The Hague, The Netherlands.

Due to the flexibility of nodegoat, it can be used for a wide range of different kinds of research projects. This means that there is rarely only one project at a university or research institute that wants to use nodegoat as their primary tool of research. To be able to facilitate these multi-project configurations, we have been offering various installation packages and service level agreements in the past years. To streamline our services we have formalised these packages in three different nodegoat products: nodegoat One, nodegoat Grow, and nodegoat Go.

nodegoat One is suitable for institutes that want to run a single nodegoat project. nodegoat Grow is suitable for institutes that want to run a specific amount of nodegoat projects that each have their own database. nodegoat Go is suitable for institutes that want to offer any amount of nodegoat research environments to their staff and students.[....]

nodegoat Open-Source

CORE Admin

Work on nodegoat started in October 2011 when Joep Leerssen approached Pim van Bree and Geert Kessels to develop a visualisation of a set of historical letters. The first version of this visualisation was a diachronic spatial data visualisation built in JavaScript. This visualisation still runs at http://projects.lab1100.com/labmap/.

Based on this project, Pim van Bree and Geert Kessels founded the company LAB1100 to continue to work on data related topics within the realm of the humanities.

Since 2011 LAB1100 has developed an online research environment that is able to host research data as well as provide various modes of analysis and visualisation. This online research environment was initially called the 'Chrono Spatial Research Platform'. In 2013 its name changed to nodegoat (which is now a registered trademark in the EU and US).

From 2012 onwards, free individual hosted accounts have been provided to scholars who want to use nodegoat to host, analyse, and visualise their data. These accounts can be requested here. We currently provide over a thousand of individual scholars with a free personal research account. You can explore a number of use cases here.[....]

With this poster, nodegoat will be present at this year's ADHO DH conference in Montreal, Canada.

We also present a long paper on the iterative data modelling methodology. We'll talk about the benefits of this approach in relation to teaching data modelling and data modelling as a research practice. This presentation is based on the three blog posts we published earlier this year:

More info on the conference session in which we present our paper can be found here. Below you find the slides and abstract of the paper.[....]

nodegoat API

CORE Admin

As a result of our cooperation with nodegoat's institutional partners, we have been able to develop a RESTful API for nodegoat.

The API provides an additional interface to query and store data to your Projects in nodegoat. We have integrated the API with nodegoat's core functionalities and have optimised it for large operations. The API can also be used to update the data Model, which allows you to update specific attributes of a Type, or upload a whole data Model with multiple Type templates in one go.

You can use the Project settings to configure what parts of your data are exposed through the API. The API can be configured to require authentication or allow for public access.

Documentation for the API is available via the nodegoat Documentation. To learn how you can query your data to use it in other applications, see: https://nodegoat.gitbooks.io/documentation/content/usage/API/query.html. To learn about storing your data using the API, see: https://nodegoat.gitbooks.io/documentation/content/usage/API/store.html.

In case you want to use the API with your own research data, get in touch!

We have enabled the API for a demo domain. You can access this domain by logging in to nodegoat.net with the username 'demo' and password 'demo'. The following cURL commands give you a JSON package with the information that has been entered on the French intellectual Ernest Renan. You can also click on the URL to view the output in your web browser.

Iterative Data Modelling

CORE Admin

In the past years, we have given various nodegoat workshops to groups of scholars and students. Even though the entry level of the participants varied from workshop to workshop there were similar challenges that emerged every time. These challenges can be grouped into the following three questions:

  1. What is a relational database?
  2. My material is very vague/ambiguous/uncertain/contradictory/unique/special, how can I use this in a database?
  3. How do I use the nodegoat interface?
nodegoat Workshop at the University of Luxembourg.

Since most of the workshops we give are nodegoat-specific, we aim to teach participants how to do data modelling from within the nodegoat interface. Because of this, and as a result of the usual time constraints (often half a day), we have to leave the first two fundamental questions largely untouched. To remedy this, we have written two blog posts in which we aim to cover the first two questions. The third question is being addressed in the nodegoat video tutorials, the FAQ & forum, and in the near future the documentation.[....]
