Dagstuhl Artifacts Series (DARTS)

In order to satisfy the standards of our series, please note that we expect an affiliation at least to contain a city and country (for locations in the United States also the state), so we usually don't support requests asking for removing this kind of information from an affiliation.

For organizations with multiple locations please choose the location where you have been most of the time physically when carrying out this work.

We hope that our completion of affiliations according to the above criteria facilitates the contacting of authors as well as the assignment of a work to individual locations, and - last but not least - serves the harmonization of affiliations across the entire volume.

• Authorized users only appear within the Submission Server as far as the processing of the paper (submission, approval) is concerned.
• They won't appear in the metadata of the published article! (The metadata will be read from the submitted LaTeX code instead.)
• Authorized users marked with the symbol are already registered to the system. Users without this symbol have been invited to the system but have not created a user account yet.
• Given the above, it is not necessary to synchronize name and email of authorized users in any way with the data of actual authors. (They rather synchronize automatically with the user accounts on the Submission Server).

At the beginning of the submission process, the submission system has only limited information about the actual authors of the article. But on each upload, the metadata of the paper (including authors) are updated. Before the publication, the authorized users are asked to confirm (or revise, if necessary) the metadata. In more detail:

• Before the first successful upload of the LaTeX sources of an article, the list of authors shows the authorized users or corresponding authors (if available).
• After each upload, the list of authors is temporarily extracted from the LaTeX sources. Since this automatic extraction could fail or be faulty, the final authors' information is only extracted by the Dagstuhl Publishing Team during the final typesetting and imported before Author Approval. During Author Approval, you can request corrections on these data.
• Finally (usually 3 weeks before the publication), the authors are explicitly asked to approve the extracted metadata. At this stage, minor modifications or necessary corrections are still possible.

• No LaTeX source submitted yet? Don't worry about any errors here. Every time you upload a LaTeX source, the list will automatically be updated according to the \author macros in your file.
• Otherwise: Simply correct the \author macros in your LaTeX file and do a re-upload. If the error persists, please make sure that the \author macros are contained in the top level of your main LaTeX file (outside \if conditionals) and contain plain data (i.e. preferably no self-defined macros).
• Note: In any case, Dagstuhl Publishing asks you to confirm/correct the metadata before the work is officially published.

Dagstuhl Publishing uses BibTEX to format references. Thereby the BibTEX style plainurl is used for BibTEX processing (\bibliographystyle{plainurl}).

• The bibliographical entries should be complete according to BibTEX standards, (no warnings or errors should occur).
• Whenever possible, references should contain an external link, e.g., DOI (preferred) or URL
• It is highly recommended to use dblp to enrich the references and, e.g., add missing DOIs.
• Please do not change the bibliographic style! Author-year citations are not allowed. (So the natbib package is not supported by the current styles of Dagstuhl Publishing.)
• Unreferenced bibliography entries will be removed, \nocite{*} is forbidden.
• Submitting a bbl-file only or an inline-bibliography is not sufficient.

The metadata associated with a DOI may not be available in all services, especially in the context of Crossref. The reason for this is that we use DataCite as our DOI registry and not CrossRef. CrossRef is certainly the largest registry for DOIs, but there are a few others (see https://www.doi.org/the-community/existing-registration-agencies/).

However, our data can be retrieved in a number of ways. DataCite offers several search options and APIs that are similar to those of CrossRef, see for example https://commons.datacite.org/.

Alternatively, you can of course retrieve the complete set of metada directly from us (https://drops.dagstuhl.de/metadata) or the basic data set from dblp (https://dblp.org).

Please note that in the metadata form there are funding fields at the bottom of each author block as well as a general funding field at the very bottom of the form (see "Additional Metadata").

In the PDF, all of these funding fields are merged to one funding block on the title page, where the author-specific funding fields are automatically preceded by the author's name.

Important! Please do not double funding information by repeating in the general field what is already contained in the author specific ones and vice versa.

As general rule of how to distribute funding information on the different fields consider the following: If a funding is clearly assigned to an author, please use the author-specific funding block. You should only deviate from this rule if the funding block on the title page of the PDF becomes unnecessarily long due to the fact that several authors have the same funding information.

The left justification of the equations is not random but part of the LIPIcs style and the other styles of Dagstuhl Publishing. We decided some years ago that we prefer text-like content (incl. equations and captions) to be left-justified and not centered. In contrast, figures and tables are centered. See also the LIPIcs Author Guidelines:

https://submission.dagstuhl.de/styles/instructions/lipics

The alignment of the equations is thus a deliberate style decision of the series. Therefore, we cannot comply with any request for centering.

• The values of the grey (disabled) input fields can only be modified by editing the LaTeX source code and performing a re-upload of the paper afterwards.
• For your convenience, the values of the white input fields (if any) can be edited directly in the corresponding web-form (no re-upload needed). We will process these changes later during the final typesetting.

Since the automatic extraction could fail or be faulty, the final version of metadata will be extracted by the Dagstuhl Publishing Team after the typesetting is done.

In any case we ask you to confirm/correct the metadata before the work is officially published!

We try to harmonize dashes across the whole volume (even across the whole series). We clearly address this as one of our typesetting actions in the author guidelines - admittedly, at the very end, cf. p.1:21, Section 3.2 of our current author instructions for LIPIcs authors.

However, seeking uniformity is always difficult if different style guides give different advice.

The University of Oxford Style Guide explicitly says on p. 13:

m-dash
Do not use; use an n-dash instead.

n-dash
Use in a pair in place of round brackets or commas, surrounded by spaces.
Use singly and surrounded by spaces to link two parts of a sentence, in place of a colon.

Generally, it seems that in British English the " -- " variant is preferred over "---", whereas in American English it is just the opposite. (It seems, however, that there is no uniform opinion on this in either language area.)

Hence our replacement ("---" -> " -- ") follows at least one of the accepted style guides.

Please note that a subject classification contained in your LaTeX file may be considered invalid if we cannot literally match an entry from the 2012 ACM Computing Classification System in a \ccsdesc{...} macro in your LaTeX file. (That can have many causes.)

To save you the trouble of a new upload, please find the "Search ACM Classifications"-input field in the upload form. There you can search for the corresponding valid classification. (By using the last part of the intended classification as a search term one usually ends up with a good pre-selection.)

Note that invalid classifications will automatically be removed from the LaTeX code during the final typesetting by Dagstuhl Publishing.

• During this period (of usually 3 working days) authors are shown a pdf preview of their paper along with the extracted metadata.
• authors approve or ask for (minor) corrections
• Dagstuhl Publishing asks authors to help with resolving issues detected during the final typesetting (if any)
• Dagstuhl Publishing checks the correction requests and revises the papers (if possible)
• Authors are informed at an early stage on the dates and can authorize other persons to do the approval on behalf of them (if necessary).
• Editors are not involved in this process, but can see the revisions in a change-log (during the editor approval step).

If you click on "Save and Finish Author Approval", we are notified about your request.

Then we check if the proposed changes can be implemented. (Do they comply with the standards of the series? Are there no consistency issues? Are there no technical limitations, e.g. charset problems, ...).

In case these checks are positive, we implement the changes both in the metadata (if necessary) AND in the LaTeX file.

In any case, even if we cannot make the requested changes, you will be informed by E-mail.

As soon as some authorized user (usually you or your co-authors, if any) finishes the approval request and submits it to Dagstuhl Publishing (this happens at the end of Step 2), we are notified about your request.

Then we check if the proposed changes can be implemented. (Do they comply with the standards of the series? Are there no consistency issues? Are there no technical limitations, e.g. charset problems, ...).

Here is an example of a completely filled author macro:

\author{John Q. Public}
{Institute of Pure Nonsense, Dummy University, Atlantis
 \and \url{http://www.myhomepage.edu}}
{johnqpublic@dummyuni.org}
{https://orcid.org/0000-0002-1825-0097}
{funded by the man in the moon.}

Please note:

• Use full first and last name.
• City and country belong to the minimum requirements on an affiliation.
• If an author has several different affiliations, please clearly separate them with the keyword \and.
• E-mail, ORCID, and funding are optional.
• Author macros cannot be shared! Please use separate author macros even if two or more authors have the same affiliation!

This macro sets the page header of odd pages, which is an abbreviated version of the concatenated author string. Sample usage:

\authorrunning{J.\,Q. Public, A.\,E. Access, and E. Example}

Please...

• abbreviate first names
• in case of middle initials: use \, as illustrated in the example
• be consistent with the \author macros
• in case of 2 authors: concatenate with " and "
• in case of 3 or more authors, see the sample for concatenation
• in case of overfull \hboxes: use the name of the first author and "et al."

Dagstuhl Publishing uses BibTEX to format references. Thereby the BibTEX style plainurl is used for BibTEX processing (\bibliographystyle{plainurl}).

• The bibliographical entries should be complete according to BibTEX standards, (no warnings or errors should occur).
• Whenever possible, references should contain an external link, e.g., DOI (preferred) or URL
• It is highly recommended to use dblp to enrich the references and, e.g., add missing DOIs.
• Please do not change the bibliographic style! Author-year citations are not allowed. (So the natbib package is not supported by the current styles of Dagstuhl Publishing.)
• Unreferenced bibliography entries will be removed, \nocite{*} is forbidden.
• Submitting a bbl-file only or an inline-bibliography is not sufficient.

\ccsdesc{...} is for classification information following the ACM 2012 Computing Classification System. Sample usage:

\ccsdesc{Theory of computation~Proof complexity}
\ccsdesc{Theory of computation~Quantum complexity theory}

Please feel free to use our ACM 2012 Subject Finder to search for appropriate classifications and to generate the necessary LaTeX code.

Using this macro, you specify the copyright holder (appearing at the bottom of the title page) which is usually the team of authors. Sample usage:

\Copyright{John Q. Public, Adam E. Access, and Eve Example}

Please...

• use full first and last names
• be consistent with the \author macros
• in case of 2 authors: concatenate with " and "
• in case of 3 or more authors, see the sample for concatenation

This macro should be used to capture general (i.e. not author-specific) funding information.

If a funding can be clearly assigned to an author, please use the last part of the \author macro instead.

Sample usage:

\keywords{Theory of Everything, indefinite Metrics, abstract Nonsense}

Please note:

• comma as delimiter
• first word and every proper noun should be capitalized

We expect you to provide your DARTS artifact as a single (compressed) file. To calculate the md5-sum of this file on your local machine, please type:

• md5 [artifact_filename] in a Linux/Mac OS terminal
• CertUtil -hashfile [artifact_filename] MD5 in a Windows Shell

The output should be a 32 byte hex string. Use this string as argument of the mdsum-macro, e.g., \mdsum{b157da23549e1d718bb16d22ded6d941}.

In order to satisfy the standards of our series, please note that we expect an affiliation at least to contain a city and country (for locations in the United States also the state), so we usually don't support requests asking for removing this kind of information from an affiliation.

• waits for an explicit approval of the editors to expose the web-portal to the public

The editors check everything carefully and ask for minor changes, if necessary.

When approved, the volume will be officially published.

First note that there are no automatic actions triggered when the editor submission deadline has passed! You actually decide on when to hand over the volume to Dagstuhl Publishing. (However, if you miss the deadline, we cannot guarantee a timely publication.)

Your tasks here are:

• checking for completeness and remind delayed authors on submitting their papers
• checking the order of papers (re-ordering, if necessary)
• checking for/setting the correct paper categories (e.g. Invited Talk, Extended Abstract, ...)
• writing a preface and including it into the pre-generated front matter provided by the Submission System
• handing over the volume at the specified date (editor submission deadline) to Dagstuhl Publishing
• no need to edit LaTeX sources submitted by the authors manually (although the possibility is given)

First note that the specified author submission deadline does not automatically trigger any actions (like closing the submission). However, it is the deadline communicated to the authors in E-mails generated by the system. Actually, you decide on when to close the submission manually.

The editor's tasks during paper submission are:

• editors monitor the progress of paper submissions (there is an E-mail notification)
• editors send reminders (guided by the Submission Server) in case of incomplete submissions
• editors check the page limits (if any) and encourage the authors to comply with the style guidelines
• editors write a preface and include it in a pre-generated front matter template
• editors guarantee a handing over of the volume within the agreed deadline
• no need to check the submitted LaTeX sources manually (there are some automatic checks on upload)
• no need to do any kind of typesetting
