1. Status and Planning
2. Development
3. Kitodo User Survey

## 0 Quick Recap

→ We want to bring OCR-D into mass digitization.

- Project goals:
- scalabe and robust OCR-D Web Service
- improved Quality Metrics
- integration with Kitodo (   .Production    /   .Presentation )
- aligned to the requirements of the Community

---

## 1 Status

- Commenced 01 Oct, staged entry of core team members:
1. Katya Rykhlinskaya (Community Outreach): Oct 2021
2. Robert Sachunsky (DEV OCR-D): Nov 2021
3. Sven Marcus (DEV Web Service): ~Dec 2021
4. Markus Weigelt (DEV Kitodo.Production): ~Jan 2022
5. H. Sidiropoulos (DEV Kitodo.Presentation): ~mid Jan 2022

---

## 1 Planning

- First Phase – independent Tiers:
- Assess User Requirements
- Network Implementation (coordinated)
- Scaling + robustness (coordinated)
- Quality/Error interfaces, Quality Metrics
- Fill technological gaps (GT, OLR, Backlog, New Wrappers)
- Second Phase – additional, dependent tiers:
- UI for Control and Visualization
- Kitodo.Production Module
- Kitodo.Presentation Interfaces
- Experiments on Workflow Optimization

## 3 User survey
### General data

- workshop for Kitodo user community
- open [survey](https://limesurvey.rz.tu-bs.de/index.php/444955) to understand the needs concerning OCR-D integration
- 33 detailed questions regarding:
- type/quantity/quality of data
- technical constraints on software
- Kitodo versions/migration and servicing
- preferences regarding service model
- previous/other OCR experience
- preferences regarding workflow and monitoring UI
- preferences regarding quality vs. speed
- required output formats and interface for manual correction
- demand for OCR-on-demand functions
- 24 participants (so far!)

---

## 3 User survey
### Preliminary results (example)

- questions regarding kind of materials to be digitalized, format and language

→ broad spectrum of materials to process (including newspapers and magazines), fonts and languages

---

## 3 User survey
### Preliminary results (example)

- questions regarding expected characteristics of OCR process

→ need for both options "quality first" and "quantity first"


---

## 3 User survey
### Summary

- survey still active → results not fully analysed yet

- information will guide Kitodo/OCR-D design and implementation

- everyone welcome to [participate](https://limesurvey.rz.tu-bs.de/index.php/444955)
