The CCPN Project
• Collaborative Computing Project for NMR
• Started in 1999
• Unifying platform for NMR software
similar to CCP4 for X-ray crystallography
• Community-based, open-source, software
development
Context
High-throughput structural biology relies on
software pipelines. Programs that do
various tasks must be combined,
preferably so that there are alternative
programs for each task. Yet, connecting
one program to another can be quite
difficult in practice. Often all you have is
an incomplete set of partial and badly
maintained conversion scripts.

Task1

Task3
Disunified Software
• Every program does things its own way.
- proprietary data formats.
• No provision for data exchange.
- limited choice, and data loss.
• No provision for data harvesting.
- lost and neglected data.
• No basis for task or code sharing.
- you must keep re-inventing the wheel.
• Software pipelines require interoperability.
CCPN Activities
• Data standards and software integration
– Data Model with associated subroutine libraries.
– Tools – a framework for data modeling.
– Collaborations
• Software development and distribution
• Meetings and workshops
■ CCPN aims
■ Data standards
■ Code Generation and libraries
■ Data Model structure
■ API details

Data standard - objectives
– Lossless data transfer between programs
– Completeness, integrity of data
– Data harvesting
• All data retained till deposition
• Allows data mining

CCPN focus
• Data creation
rather than querying final results
• Applications
rather than documents
• Information store rather than message passing
• Full details
rather than summaries
• Precise specifications
Framework requirements
• Precisely defined standard
– A single central description
– Validation directly against standard
• Support many parallel implementations
• Ensure data consistency and validity
• Easy to maintain and modify
• Programmer-friendly
Chosen approach
• Model Driven Architecture
• Abstract data model – UML
• No stable format – stable API
– easier to maintain as model changes
• Support XML and SQL, underneath
• Support several programming languages
• Automatic code generation to make it feasible
Preferences
• All science in one, shared multipackage model
made in collaboration.
• API, storage and I/O libraries reflect model
exactly
• CCPN framework provides storage, I/O and
all bookkeeping
• Others do science and user interaction
• Program-specific needs in extensions

CCPN code generation
The applications that the user sees remain independent, but do all their
data access through the CCPN APIs. These in turn store and load
the data transparently from disk (XML or database).
All subroutine libraries are generated fully automatically from an
abstract logical model, that describes the structure and
characteristics of the data without reference to the implementation.
The logical model is made in UML from a series of connected
packages, designed by teams of domain specialists for different
scientific domains.
All generated code is by definition consistent, since it derives from the
same model. Code generation is fully automatic, and the resulting
subroutine libraries can be used directly, without manual tweaking.
Implementation-specific code is stored as code snippets in tagged
values inside the UML; it amounts to less than 0.5% (character
count) of the total.
The API implementations are object oriented and are guaranteed to be
stable – unlike the underlying storage formats. Storage is
transparent, and applications should work equally well with either a
file-based or a database implementation. Some features, like
transaction handling, roll-back, or access control, will only be
properly implemented in database implementations.

CCPN APIs
• Application Programming Interface
– Is the standard
– Subroutine library
– Data accessed in memory
as if stored inside the data model
– Classes and objects, with functions (get, set, …)
• Comes with:
– Integrated, transparent I/O (file or database)
– Complete validity checking
– Protection against casual change
(data encapsulation)
– Versioning and backwards compatibility
Developer Benefits
• Standard shared by many programs
– Comes with reference data
• No need to write I/O or checking code
• Concentrate on the science, not book keeping
• Extendible
– Program-specific data in all objects
– New model packages
• Functionality
– Utility functions (e.g. Molecule from 1-letter codes)
– Notification system (for GUI)

•
‘get’ and ‘set’ (Attributes and links)
‘add’ and ‘remove’ (Multiple attributes and links)
‘sorted’ (Multiple unordered links)
‘findFirst’ and ‘findAll’ (Multiple links)
– Simple filtering (attribute == value)
create and ‘new’ (Objects)
– Normal and ‘factory function’ object creation
delete (Objects)
– ‘Delete’ function.
checkValid, checkAllValid (Objects)
‘current’ (e.g current NmrProject)
• API classes are strongly coupled. For efficiency reasons
object-to-object links are two-way, with information stored on
both sides, and this forces objects to interact directly with the
internal representations of objects they are linked to.
Code Generation
UML is edited in a commercial editor (ObjectDomain) that
includes a Python scripting environment. An ObjectDomainspecific script extracts the model description into a Python
in-memory representation, that is then written to disk as a
series of XML files. The UML editor is not used further, and
another one could be substituted simply by providing a new
data extraction script.
Subsequent code generation is done outside the editor. The
XML model description is read into memory as a series of
Python objects, based on the Python classes of a
MetaModel. Code generators then uses the information in
the in-memory description to generate all necessary files

Runtime implementations
File and database implementations are
organised differently, with varying use of
off-the-shelf code. For both
implementations a large fraction of eth API
code is taken up by constraint checking, to
make sure that data remain consistent
with the rules embedded in the model.

Main Concepts
• Model is Normalised
– Every piece of information stored in only one place
• Classes and Objects
– Inheritance and subtypes (single inheritance only)
– Elements (attributes and links) and operations
Most operations not entered explicitly
– Classes may be abstract
• Attributes
– String, numeric, special complex types
– Compare by value
•
Links
–
–
–
–
Connection to other objects
Generally two-way
All objects have identity
Most –to-many links are sets

More Concepts
• Parent links
– Join all objects in a tree,
rooted in MemopsRoot/Project
• Local keys
–
–
–
–
Uniquely identify an object relative to its siblings
One or more attributes or links
Use serial number if no other candidate
Combined to form global keys
• Derived attributes and links
– Not stored, but calculated when needed
– Behave like normal attributes

TopObjects and Implementation
• TopObjects
– Every package has a TopObject
(e.g. ChemComp, NmrProject)
– TopObjects are children of MemopsRoot/Project
– File Implementations have one file per TopObject.
– No links between objects from same package with
different TopObjects
– TopObjects have universal identifiers (GUID)
• Implementation package contains no real
data, only file and database locations

Constraints
•
Frozen (unchangeable) attribute
– Change-once to be introduced
•
Cardinality
– 0..1, 1..1, 2..2, n..m, * (0..infinity)
•
Collections
– Unique, unordered = set
– Nonunique, ordered = list
– Unique, ordered = list with uniqueness checking
• Ad-hoc (handcoded) constraints
– DataType (value)
– Attribute and Link (object and value)
– Class (object)
•
Constraints are always enforced.
Handcode
•
In constraints on DataType, Class, or Element
•
In function bodies
– May override an autogenerated function
e.g. a getter for a derived element
– May define a new function, e.g. MemopsRoot.saveAll
•
To be added at the end of constructors,
e.g. to create more objects automatically
•
To be added at the beginning of delete,
e.g. to prevent delete in some situations.
• Handcode is entered separately for each language

■ CCPN aims

■ Data Model structure
■ API details
■ Status, resources and plans
■ Credits
API facilities
• Data access only (get, set, create, delete, …)
– CCPN does not do things with the data –
that is up to you
• Data Encapsulation
– Internal lists etc. not returned outside objects
• Functions only defined where they make sense
– No ‘add’ functions for frozen or 2..2 links
• Functions raise error if they cannot do their job
API examples
Examplkes are java specific. Many (but not
all) would look identical in Python. In
Python we also use keyword arguments,
and allow the standard Python syntax
( value = obj.attr, obj.attr = value).

Get
• x = myChemComp.getMerckCode()
returns value
• x = myChemCompVar.getChemAtoms()
returns list or set of values
• Function always present
Set
• myChemComp.setMerckCode(x)
sets value – x may be null if constraints permit
• myChemCompVar.setChemAtoms(atList)
– accepts any collection values
– removes old values and sets new ones
– only function that can reorder ordered elements
• Function not present for frozen elements,
or for parent or child links
• May be present for derived elements
• First checks cardinality and handcoded constraints
(unless called from a constructor)
Add, remove
• myChemCompVar.addChemAtom(atom)
myChemCompVar.removeChemAtom(atom)
• Function not present for frozen elements,
parent elements, child elements,
or where cardinality is n..n.
• May be present for derived elements
• First checks cardinality and handcoded
constraints (unless called from a constructor)
Sorted and current
•
myList = myChemComp.sortedChemAtoms()
myList = myChemCompVar.sortedChemAtoms()
– For child links sorts on local key (here ‘name’, ‘subtype’)
– For other link sorts on full key (here ‘molType’, ‘ccpCode’, ‘name’,
‘subtype’)
• Function present for unordered multiple links
• myChemComp = myProject.getCurrentChemComp()
• Only between MemopsRoot/Project and TopObjects.
• Remembered between sessions
findFirst and findAll
•
myBond = myChemComp.findFirstChemAtom(constraintMap)
•
myAtom = myChemComp.findFirstChemAtom(“name”, “HA”,
“subType”, 1)
•
myAtom = myChemComp.findFirstChemAtom()
•
atList = myChemComp.findAllChemAtoms(“name”, “HA”)
– Selects or filters based on ‘self.keyword == value’
– findFirst mainly used where there is at most one element that fits,
or where you want a random element.
• Function present for all multiple links, also if derived
Delete
• myObj.delete()
– sets myObj.isDeleted=True
– removes all known links from undeleted
objects to myObj
– Recursively deletes any object that:
• has a frozen or add-once link to myObj
(this includes all children)
• has a mandatory (n..n) link to myObj
• has an n..m link to myObj if there are fewer than n
objetcs left in the link
Object Creation
• newLinkAtom = new ChemAtom(myChemComp, “HA”, 2)
• newLinkAtom = myChemComp.newChemAtom(“HA”, 1)
• newAtom = myChemComp.newChemAtom(attrLinkMap)
•
Suspends most validity checking,
but calls myObj.checkValid() afterwards.
Validity Checking
• myObj.checkValid()
– Checks that object and their attributes and links satisfy
cardinality and handcoded constraints
• myObj.checkAllValid()
– recursively calls checkValid for myObj and all child objects.
• If called as ‘checkValid(True)’
either function also checks DataType constraints,
and that two-way links are self-consistent.
– ‘complete=True’ is slow!
