Very minor hotpatch release to include the new local dashboard.
- New dashboard version (v6.0.9) which includes various fixes and enhancements, like the ability to properly close pull requests.
This release introduces a docker-compose deployment method which gets you all components of a fully-featured terminusdb setup:
- TerminusDB - the main database.
- VectorLink (experimental) - a database sidecar dedicated to storing, indexing and retrieving vectors by similarity, used for AI-enhanced search.
- terminusdb-change-request-api - an API for working with change requests.
- Terminusdb-dashboard - our dashboard for managing terminusdb, which now experimentally supports AI search and change requests.
Beyond that, this version brings various fixes and enhancements to our GraphQL support, our schema checking and migrations, and the document interface. Please read the detailed list below.
- multi-level graphql hierarchies were not always returning all objects.
- properties with prefixes didn't work properly in graphql.
- graphql reverse links did not work with sanitized names.
- graphql incorrectly filtered out 'id' from user-defined types.
- docker-compose now comes bundled with vectorlink, local dashboard and pull request API.
- properties can now be inherited from multiple superclasses, and even redefined in a subclass, as long as they form a type-compatible hierarchy. The strictest form is actually applied. If the subclass defines a property that is not at least as strict as what was defined in the supers, this results in a schema error.
- graphql can now be made to not return subsumptions through the generated
include_childrenargument. - new environment variable
TERMINUSDB_TRUST_MIGRATIONSwill ensure that instance data is not re-checked when schemas change due to migrations, as migrations should in principle not result in any errors. As the migration feature is still relatively new, the default here is false, meaning that without this environment variable, all schema changes result in a recheck of all existing instance data. In the future, this default will likely change.
- schema migration scripts now support changes to class hierarchies and key strategies.
- the graphql engine now keeps a small cache around of recent schemas to speed up repeated queries.
- graphql filters now support deep matches on IDs.
- document API has a new parameter
idson GET allowing you to submit a list of documents to retrieve at once.
- Fix ordering of graphql stringy numbers
- Adding type information to decimals
- Adding a correct diff using out of band value
- Prevent reserved words in GraphQL from being used
- Fix loading of triples
- Add support for the TerminusDB semantic indexer for AI search capabilities
- Add ability to merge base layers with the
concatcommand
- Reduced memory usage
- Remove Google Analytics in Dashboard
- Unused optional properties would cause GraphQL to fail
- Enums were not working properly for collection types in GraphQL
- Incorrect version checking on system graphs caused superfluous graph updates on startup
- Modifications of classes with
@oneOfwould leave stale objects in the schema graph - Diffing sets now works
- Fix error reporting when pushing nonexistent remotes
- GraphQL did not work properly with
@oneOfproperties - Memory leak in document API
- Crash when processing several compressed requests in the same session
- On schema modifications, a migration will be inferred when possible.
- New options added to document interface
**
allow_destructive_migration: Allow for inference of migrations that will also modify instance data. If set, the schema modification will also automatically transform any instance objects already in the database. **require_migration: This will cause the request to fail for schema changes for which no migration can be inferred.
- diff endpoint now has
startandcountoptions for paged results - Improve memory footprint when retrieving lots of documents through the document API
- Support JSON objects in GraphQL

- Adding Patch Endpoint for Resources
- Implement pinned organization ENV variable to keep data products of whole organizations/teams in memory
- On replace, schema documentation entities were not cleaned up properly
- Fix support for ne (not equal) operator in graphql
- Document replacement allowed insertion of nested documents, even without the create option specified. We decided that this was a bug, and made it so that this now errors, unless the create option is specified. This is backwards-incompatible, but we believe that this is the correct behavior. If your code relies on nested documents being inserted, make sure you specify the create option. Note that this is just about nested documents which are top-level types. Subdocuments are not affected.
- Introduced support for a grpc label store as an alternative to file-based label lookup terminusdb-labs/terminusdb-grpc-labelstore
- Implemented local clone

- Delete the stale database if a clone fails
- Fix SSL issues in fetch and push: newer version of openssl errors when a connection is closed unexpectedly
- Fix accidental insertion of duplicate nested documents
- Fixed GYear support
- This release changes the storage format of TerminusDB. After installing this version, you will also need to upgrade your storage directory, or the server will not start. A conversion tool is provided at terminusdb-10-to-11. This is also bundled with terminusdb-bootstrap.
- TerminusDB 11 now responds to
xsd:integer,xsd:decimal, and all of the unbounded sub-types of these two objects in the document interface with strings. This is because many (even most) JSON libraries can not handle arbitrary precision integers, and (few if any) can handle arbitrary precision floats. It should still be possible to submit documents using integers or floats, but when returned they will be strings.

- By default only one witness is now returned in WOQL queries in which the resulting database violates schema constraints.
- Improved the API for organisation management
- Improved CORS handling on some calls
This is largely a bug fix and cleanup release. We focused on improving error handling and code maintanability.

- Posted files can now be processed by WOQL.get
- Fixed API endpoint for WOQL.put which allows us to dump to CSV
- Errors are now largely structured as JSON-LD carrying with them a type which
is defined in
terminus-schema/api.owl.ttl. This should make it much easier for clients to determine the exact meaning of an error, and allows Error reporting to be documented in an ontology.
- Handling of floating point numbers has been improved to stop some spurious type errors.
- Fixed a utf-8 encoding issue encountered when loading remote csvs.
- New TerminusDB Console
- Bug fixes
- New version of terminusdb-console
- Implemented Clone, Push and Pull
- The
TERMINUSDB_SERVER_PUBLIC_URLenvironment variable is now ignored. TerminusDB is now fully location-agnostic. - Added
TERMINUSDB_SERVER_PACK_DIRenvironment variable, determining where swi-prolog packages will be installed. This was added to make it easier to offer alternative distributions of TerminusDB in the future.
- CORS handling has been changed to reflect Origin on authenticated requests.
- Provide HTTPS support and the ability to set your own certs
- The built-in web console now works on different ports
- The built-in web console now works on different hosts
- Resolution of resource descriptors now attempts to resolve relative to the current context before trying to resolve as an absolute path.
- woql:Size was using a database path predicate which was not imported causing it to fail.
TerminusDB Server now implements databases as a tiered structure which tracks deltas on collections of graphs. This tiered structure includes:
- Meta data graph: Holds information about the local and all remote repositories assocated with a given database.
- Commit Graph: A graph containing information about all commits, their authors, a comment, and associated branches.
- Instance and Schema Graphs: These graphs containing the actual data.
These new structural changes to the underlying store allow users to perform a number of git-like operations. This includes:
- Time-travel on databases: You can run queries, browse documents or view the schema at any previous commit.
- Branching: You can branch from any current branch or reference (a previous commit).
Several new querying capabilities have been added:
- Regular path queries allowing the user to query recursively using combinations of intermediate predicates resulting in both end-point nodes and the particular path as a list of edge objects.
- Database size and triple count can be queried
- You can choose a specific resource to query including: the meta-data graph, the commit graph, a collection of instance or schema graphs, or a particular commit.
-
The storage approach has changed dramatically and so previous databases can not be read directly by the new TerminusDB. Upgrades require re-ingesting data.
-
The previous version of TerminusDB used JSON as an interchange for WOQL ASTs. The current version uses JSON-LD, which is a serialisation of RDF. This enables us to store WOQL queries in a database and provides a schema documentation of the WOQL query language.
- Transactional logic in TerminusDB 1.0 had surprising outcomes when backtracking over inserts. We currently treat inserts as non-backtracking destructive updates.
- WOQL.when is not required in order to perform updates.
