+# Goals and Related Projects
+
+## Goals and Ecosystem Niche
+
+For the Internet Archive use case, fatcat has two primary use cases:
+
+- Track the "completeness" of our holdings against all known published works.
+ In particular, allow us to monitor and prioritize further collection work.
+- Be a public-facing catalog and access mechanism for our open access holdings.
+
+In the larger ecosystem, fatcat could also provide:
+
+- A work-level (as opposed to title-level) archival dashboard: what fraction of
+ all published works are preserved in archives? KBART, CLOCKSS, Portico, and
+ other preservations don't provide granular metadata
+- A collaborative, independent, non-commercial, fully-open, field-agnostic,
+ "completeness"-oriented catalog of scholarly metadata
+- Unified (centralized) foundation for discovery and access across repositories
+ and archives: discovery projects can focus on user experience instead of
+ building their own catalog from scratch
+- Research corpus for meta-science, with an emphasis on availability and
+ reproducibility (metadata corpus itself is open access, and file-level hashes
+ control for content drift)
+- Foundational infrastructure for distributed digital preservation
+- On-ramp for non-traditional digital works ("grey literature") into the
+ scholarly web
+
+## Scope
+
+The goal is to capture the "scholarly web": the graph of written works that
+cite other works. Any work that is both cited more than once and cites more
+than one other work in the catalog is very likely to be in scope. "Leaf nodes"
+and small islands of intra-cited works may or may not be in scope.
+
+fatcat would not include any fulltext content itself, even for cleanly licensed
+(open access) works, but would have "strong" (verified) links to fulltext
+content, and would include file-level metadata (like hashes and fingerprints)
+to help discovery and identify content from any source. File-level URLs with
+context ("repository", "author-homepage", "web-archive") should make fatcat
+more useful for both humans and machines to quickly access fulltext content of
+a given mimetype than existing redirect or landing page systems. So another
+factor in deciding scope is whether a work has "digital fixity" and can be
+contained in a single immutable file.
+
+## References and Previous Work
+
+The closest overall analog of fatcat is [MusicBrainz][mb], a collaboratively
+edited music database. [Open Library][ol] is a very similar existing service,
+which exclusively contains book metadata.
+
+[Wikidata][wd] seems to be the most successful and actively edited/developed
+open bibliographic database at this time (early 2018), including the
+[wikicite][wikicite] conference and related Wikimedia/Wikipedia projects.
+Wikidata is a general purpose semantic database of entities, facts, and
+relationships; bibliographic metadata has become a large fraction of all
+content in recent years. The focus there seems to be linking knowledge
+(statements) to specific sources unambiguously. Potential advantages fatcat
+would have would be a focus on a specific scope (not a general-purpose database
+of entities) and a goal of completeness (capturing as many works and
+relationships as rapidly as possible). However, it might be better to just
+pitch in to the wikidata efforts.
+
+The technical design of fatcat is loosely inspired by the git
+branch/tag/commit/tree architecture, and specifically inspired by Oliver
+Charles' "New Edit System" [blog posts][nes-blog] from 2012.
+
+There are a whole bunch of proprietary, for-profit bibliographic databases,
+including Web of Science, Google Scholar, Microsoft Academic Graph, aminer,
+Scopus, and Dimensions. There are excellent field-limited databases like dblp,
+MEDLINE, and Semantic Scholar. There are some large general-purpose databases
+that are not directly user-editable, including the OpenCitation corpus, CORE,
+BASE, and CrossRef. I don't know of any large (more than 60 million works),
+open (bulk-downloadable with permissive or no license), field agnostic,
+user-editable corpus of scholarly publication bibliographic metadata.
