mini-DML I. Presentation 1. Context 2. Catalogues & lists 3. Where is the DML ? 4. Are lists useful ? 5. Where are Cauchy seminal papers ? 6. The mini-DML project 7. Back to Cauchy II. Demonstration III. Riemann hypothesis : A case study WDML — Stockholm — June 27th, 2004 — mini-DML 1
1. C – Scientific journals exist since 1665 ( Journal des savants, Philosophical transactions ) – Mathematical journals exist since 1810 ( Annales de Gergonne) – Many digitisation projects are heavily working in order to provide that intellectual treasury to the digital age – Freely downloadable grey litterature is omnipresent WDML — Stockholm — June 27th, 2004 — mini-DML 2
– We face an exponentially growing amount of available material while – most researchers aren’t even aware of this, and... – those who know have to bookmark hundreds of websites : repositories, specialised search engines, home pages, individual journal pages, and... – they need to figure a specific strategy to localise an item in each of these sites ! WDML — Stockholm — June 27th, 2004 — mini-DML 3
2. C & Facing a similar situation, the mathematicians of the end of 19th century choosed to build lists of important published resources. – Valentin’s famous lost catalogue (1885-1910) – The Répertoire bibliographique des sciences mathématiques (1894-1912, covering 19th century) – The Jahrbuch über die Fortschritte der Mathematik (1868-1944) WDML — Stockholm — June 27th, 2004 — mini-DML 4
And later : – Zentralblatt-Math (1931- ) – Mathematical reviews (1940- ) Except in the (conjectural) first case, these lists are non-comprehensive and require an important intellectual input (choice, classification, review). Converted into databases, they are an invaluable utility for the working mathematician. WDML — Stockholm — June 27th, 2004 — mini-DML 5
3. W DML ? The DML is the virtual library of all mathematical texts available digitally, both retrodigitised and born digital. WDML — Stockholm — June 27th, 2004 — mini-DML 6
3. W DML ? The DML is the virtual library of all mathematical texts available digitally, both retrodigitised and born digital. How does an average mathematician know that such an important resource as Annals of Mathematics is currently available – at JSTOR from the first issue until 1994, – at arXiv for certain years, – at the journal home page (rare links to arXiv), – at project Euclid since 2001.

Collections A proof-of-concept implementation is presented today, based on a variety of sources of mathematical texts. The main emphasis is on long-run journals whose early production is widely unknown to MR/JFM+ZM, with special interest towards current production and preprints on the other end. – Annals of Mathematics (JSTOR URL guessed) – NUMDAM journals – One Gallica journal (Liouville up to 1880) – Few Gallica Complete works – Some project Euclid journals (Duke...) – Part of arXiv WDML — Stockholm — June 27th, 2004 — mini-DML 20
Method Retrieval of internal metadata through OAI protocol – From our home-grown catalogues (NUMDAM, Gallica, Works) – From OAI servers (Euclid, arXiv) – Possibly from less structured sources (HTML tables of contents, OCRed tables of contents...) Indexing with Edbm-2 (NUMDAM, JFM+ZM, LIMES, etc.) Exposure of the remastered metadata through an OAI server using at least 3 schemes (DC, proposed MR/ZM, minidml) WDML — Stockholm — June 27th, 2004 — mini-DML 21
Collaborations If you have scanned a long-run periodical, please provide – a unique identifier for each article, – structured basic metadata, – a simple stable URL pointing towards an introductory HTML page for each article without restriction access ; and set up an OAI server to share your e ff ort ! WDML — Stockholm — June 27th, 2004 — mini-DML 22
Wanted – Journal de Liouville (1836-1934 : Gallica ; 1935- : ?) – Comptes rendus de l’Académie des sciences (1835-1934 : Gallica ; 1935- : ?) – Monatshefte für Mathematik und Physik (1890- : DIEPER@Graz/ ? ?/Springer) – Philosophical Transactions of the Royal Society of London (1776 : JSTOR) – Commentarii mathematici Helvetici (1929 : GDZ) – Mathematische Annalen (1869 : GDZ/Springer) – Mathematische Zeitschrift (1918 : GDZ/Springer) – Journal de l’École polytechnique (1795 : X) – Etc. !
