ProseMirror/rfcs: ProseMirror RFCs
When making substantial changes to the ProseMirror core modules, we use “request for comments” workflow to formalize the design process and allow the community to join the conversation.

A substantial change may be one that introduces a new feature, deprecates something, or is otherwise complex enough to warrant some attention from the community.

This repository serves as a way to propose such RFCs, and as a log of accepted RFCs, which may be valuable for later reference.

Fossilworks: Gateway to the Paleobiology Database
Fossilworks is a web-based portal to the Paleobiology Database. The PaleoDB is a large compilation of data about fossils. It includes a dynamically integrated master taxonomic classification and site-specific distributional records. Fossilworks adds to it an algorithmically synthesized global geological time scale that enables its query and analysis tools. Some of the PaleoDB's data stem from older databases it has incorporated, such as the Smithsonian Institution's Evolution of Terrestrial Ecosystems database and the University of Chicago's Paleogeographic Atlas Project. The data set covers all parts of the fossil record, meaning that it documents marine and terrestrial animals, plants, and microfossils of all geological ages. The Fossilworks site itself includes online tools for viewing, downloading, mapping, and analyzing data records. Fossilworks was created by John Alroy (the author of this page) and is housed at Macquarie University.

On periodization: selected essays from the English Institute
I hope that I have been able to outline some of the pressures—ethical and syntactic—that are produced by attempts to represent simultaneity. Although novelists’ challenges might be different from critics’, Victorianists’ from Victorians’, and Victorianists’ from those of literary critics of other periods, historicist sentences reflect and produce, even as they work so hard to minimize, the messiness of history and its fundamental incomparability with the horizontal syntax in which our arguments unfold. I am aware that historicist sentences are also periodic sentences—and not only in the sense that they defer grammatical completion. These are sentences that in their energy, ambition, and impossibility are defined by a specifically Victorian style and relation to history taken up, with modifications and intensifications, by many Victorianists, even those who for various reasons eschew periodization. My emphasis turns out, I think, to be a little different from that of other contributors to this volume. I am less interested in rescuing history from periodization (a very useful thing) than in seeing how both depend on a fiction of simultaneity. What counts as simultaneity varies with one's task—using a date, identifying a period, or writing a periodic sentence—but all of these endeavors share a particular idea of temporality that limits what we can say about the past and about the present.

Temporality — Cultural Anthropology
Given that infrastructure is variable just like ontology (see Latour 1993), it would be good to have new sets of tools to explore its historicity. One intriguing idea—I cannot track down the original reference—is to index terms by superscripting them with dates. So, if I use the term mass in my writing, then I might write mass1905 to indicate that one author was using the Einsteinian concept of mass, while I could use mass1687 to indicate that a different author was still working from a Newtonian ontology. This is not a very useful practice within the traditional forms of knowledge expression; there are so many dates for so many ontological and infrastructural variations that no one reader would be able to keep them all in her head. However, a visualization tool that would show, for an infrastructure, what its shape and nature was at that moment would be invaluable. As you click, you get an infrastructural landscape that displays an infrastructure along with its associated ontologies.

Suffix Passthrough Explained - EZID - Confluence
Suffix Passthrough (SPT) is a feature that can dramatically reduce the number of identifiers you need to maintain. It permits one identifier registered in the Name-to-Thing (N2T) resolver to stand in for any number of identifiers formed by adding suffixes to the original identifier. Currently SPT works only for ARK identifiers.

This repository contains the RDFUnit -- a tool for test-driven quality evaluation of Linked Data quality. Further background information about the underlying Test Driven Data Quality Methodology can be looked up in the following publications: methodology (WWW2014), demo paper (WWW2014) and ontology definition (ESWC2014). The results of the methodology paper are available here . This methodology defines a set of data quality test patterns which are SPARQL query templates expressing certain common error conditions. After having instantiated such patterns for a concrete dataset possible errors of the corresponding kind can be detected.

DataCite Metadata Schema for the Publication and Citation of Research Data
The DataCite Metadata Schema is a list of core metadata properties chosen for the accurate and consistent identification of a resource for citation and retrieval purposes, along with recommended use instructions. The resource that is being identified can be of any kind, but it is typically a dataset. We use the term ‘dataset’ in its broadest sense. We mean it to include not only numerical data, but any other research data outputs.

The EZID API, Version 2
EZID (easy-eye-dee) provides an easy way to obtain, describe, and manage long-term identifiers for digital objects. It can be accessed via a web User Interface (UI) and a web Application Programming Interface (API). A few account management functions can be accessed from the UI only, but otherwise all of EZID's functionality is available through the API. This document describes Version 2 of the EZID API.

Calendar Converter
Astronomers, unlike historians, frequently need to do arithmetic with dates. For example: a double star goes into eclipse every 1583.6 days and its last mid-eclipse was measured to be on October 17, 2003 at 21:17 UTC. When is the next? Well, you could get out your calendar and count days, but it's far easier to convert all the quantities in question to Julian day numbers and simply add or subtract. Julian days simply enumerate the days and fraction which have elapsed since the start of the Julian era, which is defined as beginning at noon on Monday, 1st January of year 4713 b.c.e. in the Julian calendar. This date is defined in terms of a cycle of years, but has the additional advantage that all known historical astronomical observations bear positive Julian day numbers, and periods can be determined and events extrapolated by simple addition and subtraction. Julian dates are a tad eccentric in starting at noon, but then so are astronomers (and systems programmers!)—when you've become accustomed to rising after the “crack of noon” and doing most of your work when the Sun is down, you appreciate recording your results in a calendar where the date doesn't change in the middle of your workday. But even the Julian day convention bears witness to the eurocentrism of 19th century astronomy—noon at Greenwich is midnight on the other side of the world. But the Julian day notation is so deeply embedded in astronomy that it is unlikely to be displaced at any time in the foreseeable future. It is an ideal system for storing dates in computer programs, free of cultural bias and discontinuities at various dates, and can be readily transformed into other calendar systems, as the source code for this page illustrates. Use Julian days and fractions (stored in 64 bit or longer floating point numbers) in your programs, and be ready for Y10K, Y100K, and Y1MM!

Julian Day Numbers
4. Astronomical Julian Day Number and Astronomical Julian Date

An astronomical Julian day number is a count of astronomical nychthemerons (i.e., nychthemerons which begin at noon GMT) from the astronomical nychthemeron which began at noon GMT on -4712-01-01 JC.
For recording the time of an astronomical event the Julian day number of the nychthemeron in which the event occurs is, of course, usually not sufficiently precise. In order to specify the time of an event astronomers add a fractional component to the Julian day number, e.g., 0.25 = 6 hours (1/4 of 24 hours) after the start of the nychthemeron. An astronomical Julian day number plus a fractional component specifying the time elapsed since the start of the nychthemeron denoted by that Julian day number is called an astronomical Julian date. (The term "Julian date" has several meanings, as explained in Section 8 below.)

5. Chronological Julian Day Number and Chronological Julian Date

At some point students of calendrical science decided that the Julian day number system would be very useful in their field, provided the notion of a "day", i.e., "nychthemeron", were changed to accord with that notion as commonly used in connection with calendars. The Gregorian Calendar begins days at midnight, but not all calendars do (for example, the Jewish Calendar has nychthemerons which begin at sunset). Thus arose a variation of the Julian day number and Julian date called "chronological" to distinguish them from the "astronomical" versions.
A chronological Julian day number is a count of nychthemerons, assumed to begin at midnight GMT, from the nychthemeron which began at midnight GMT on -4712-01-01 JC. Chronological Julian day number 0 is thus the period from midnight GMT on -4712-01-01 JC to the next midnight GMT. Chronological Julian day number 2,452,952 is the period from midnight GMT on 2003-11-08 CE (Common Era) to the next midnight GMT.

Thus, although there is only one variety of astronomical Julian date (the one tied to the meridian of zero degrees longitude) there are as many varieties of chronological Julian date as there are longitudes which we might wish to use in the study of various calendars.
