• Dictionaries: Conversion of Perseus dictionaries into a structured JSON format.
• Textual Notes and Alignments: Representation of textual variants and alignments between source texts and translations.
• Syntax Trees: JSON representation of treebanks, with plans to adopt the Universal Dependency Framework tagset.
• Audio Annotations: Alignment of text chunks with recorded performances.
• Attributions/Credits: A crucial aspect of ATLAS is its ability to preserve and aggregate fine-grained credits for all annotations, ensuring proper attribution for scholarly contributions.

Future Directions

The article concludes by outlining the next steps for the project, including:

• Expanding the services offered by the ATLAS server.
• Refining and augmenting the ATLAS data available on Github.
• Integrating the ATLAS backend and user interface components developed for the "Beyond Translation" project into the existing Scaife architecture.

Overall, the article presents a compelling case for the importance of open philology and the role of sophisticated digital libraries like Perseus in facilitating deeper engagement with complex textual data. The development of the ATLAS workflow signifies a major step forward in this domain, offering a robust and scalable framework for integrating, analyzing, and presenting a wealth of philological information.

Statistikk

The Perseus Digital Library currently includes 2,669 works in 3,776 editions and translations (1,941 in Greek and 631 in Latin), with 83.8 million words in all languages (40.6 million in Greek, 16.4 million in Latin).
More than one million words of Greek and of Latin each are available in manually treebanked form.
Machine actionable metrical analyses are available for more than 250,000 lines of Greek and Latin poetry.
The accuracy of automatically generated alignments between Greek and Latin source texts and English translations is approximately 80%.

Sitater

"Sustainable integration of different categories of data has been a driving force behind the development of Perseus from the beginning."
"Our goal was to create a workflow to organize, rather than create, textual data that had been produced by, and was available in, platforms that were open but separate."
"Perseus 6 was designed to be a publishing workflow that organizes complementary data into an integrated reading environment."
"Arguably the most important challenge that we face was to preserve and to aggregate fine-grained credits for born-digital annotations."

Dypere Spørsmål

How can digital libraries like Perseus be further developed to support the study of languages beyond Greek and Latin, particularly those with less extensive digital resources?

Perseus, with its ATLAS architecture, offers a robust model for digital libraries seeking to expand beyond Greek and Latin. Here's how:

Language-Agnostic Architecture: ATLAS, built on the principles of open philology, is inherently language-agnostic. Its reliance on standards like CTS URNs and JSON for data representation allows for seamless integration of resources in any language.
Prioritizing Interoperability: The system's ability to handle diverse data formats (TSV, TEI XML, JSON) and link them through a unified interface is crucial for languages with fragmented digital resources.
Community-Driven Development: Perseus's open-source nature and use of platforms like GitHub can encourage scholars working on less-resourced languages to contribute, fostering a collaborative environment for resource creation and enrichment.
Adaptable Annotation Layers: The multi-layered annotation model in ATLAS, encompassing linguistic analysis, translations, commentaries, and even audio recordings, can be readily adapted to the specific needs and complexities of other languages.
Focus on Pedagogical Tools: Features like the alignment visualization between source text and translations, coupled with on-demand linguistic information, can be invaluable for learners of less-studied languages, providing accessible entry points into complex texts.
However, challenges remain:

Morphological Complexity: Languages with complex morphology might require more sophisticated tools than Morpheus for accurate analysis. Investing in machine learning models and rule-based systems tailored to these languages is essential.
Resource Acquisition and Digitization: A concerted effort is needed to locate, digitize, and annotate existing scholarly materials in less-resourced languages, potentially involving collaborations with institutions and individuals holding these resources.
Community Building: Active outreach to scholars working on these languages is crucial to foster adoption and ensure the platform caters to their specific research and pedagogical needs.

While the article emphasizes the value of open access and collaboration, could the reliance on platforms like Github pose challenges in terms of long-term data preservation and accessibility?

While GitHub offers significant advantages for open access and collaborative development, its use for long-term data preservation and accessibility in digital libraries like Perseus does present potential challenges:

Platform Dependency: Relying solely on a commercial platform like GitHub creates a dependence on its continued existence and policies. Should GitHub cease to exist or significantly alter its terms of service, the accessibility of the data could be jeopardized.
Data Durability: While GitHub provides version control, it is not designed as a primary data archival system. Long-term data integrity and preservation require robust strategies beyond relying solely on a platform not specifically designed for this purpose.
